The Advanced Signal Processing Toolkit (64-bit) relies on licensing activation. You must activate a valid LabVIEW 2017 Advanced Signal Processing Toolkit (32-bit) license in order to activate your copy of the Advanced Signal Processing Toolkit (64-bit) after the evaluation period expires.
Note: The software technology available on NI Labs is experimental and has not yet been released for large-scale commercial use or fully tested by NI. Refer to ni.com/labs for more information about NI Labs products.
Use the Time Frequency Analysis VIs to transform a time domain signal to a linear or quadratic time-frequency domain representation. You can extract useful information from the time-frequency domain representation of a signal, or you can process a time-frequency domain representation and reconstruct a time domain signal.
Use the Time Series Analysis VIs to perform preprocessing, statistical analysis, correlation analysis, spectrum estimation, and model estimation on a univariate or multivariate (vector) time series. You can extract useful information from the time series with different analysis methods for different applications.
Use the Wavelet Analysis VIs to perform transforms and inverse transforms between a signal and the wavelet coefficients of the signal. You can use the Feature Extraction VIs to perform denoising, detrending, probability density function estimation, peak detection, edge detection, and ridge detection on a 1D or 2D signal.
1 NI software installs VC2015 Runtime and .NET 4.6.2. Windows 8.1 and Windows Server 2012 R2 require Microsoft updates to support these items. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.
2 NI software is signed with a SHA-256 certificate. Windows 7 SP1, Windows Embedded Standard 7 SP1, and Windows Server 2008 R2 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.
Note Support for Windows 32-bit operating systems may require disabling physical address extension (PAE). To learn how this might affect your system and what actions you might need to take, visit ni.com/info and enter the Info Code PAESupport.
Select HelpFind Examples from LabVIEW to launch the NI Example Finder. The following table lists the examples for the Advanced Signal Processing Toolkit (64-bit) and the directory which contains the examples.
If the NI product you are installing uses Microsoft .NET 4.6.2, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.6.2 separately before you install NI software.
Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions. Windows 10 introduces several new capabilities and also combines features from both Windows 7 and Windows 8. For more information about NI support for Windows 10, visit ni.com/windows10.
When you install NI software on Microsoft Windows 8.1, you will notice a few additional tiles in the Apps view, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (NI MAX), and NI Launcher. For more information about NI support for Windows 8.1, visit ni.com/windows8.

LabVIEW Full/Professional Development System includes more than 500 mathematics and signal processing functions. You can find these functions under the Mathematics palette and Signal Processing palette.
The LabVIEW programming environment simplifies hardware integration for engineering applications so that you have a consistent way to acquire data from NI and third-party hardware. LabVIEW reduces the complexity of programming, so you can focus on your unique engineering problem. LabVIEW enables you to immediately visualize results with built-in, drag-and-drop engineering user interface creation and integrated data viewers. To turn your acquired data into real business results, you can develop algorithms for data analysis and advanced control with included math and signal processing IP or reuse your own libraries from a variety of tools. To ensure compatibility with other engineering tools, LabVIEW can interoperate with, and reuse libraries from, other software and open-source languages.
The aim of this paper is to investigate LabVIEW-based feature extraction methods to make a correlation between EEG and emotions. The structure of this paper is as follows: Sect. 2 includes a brief description of emotions, database signals taken from LabVIEW, and wavelet analysis. Third section includes evaluation of results. The last section involves conclusion and future works.
Emotions have been caused by internal and environmental influences. They are complex psychophysiological changes and involve so many different factors. Defining emotions is one of the difficult concepts. It is very difficult to distinguish emotions from each other. Because they are expressed differently in every culture and language, there is no clear distinction between them. There are different opinions about the number of emotions. Since the number of emotions increases or decreases for languages, races, religions, and cultures, it is hard to find the exact number of emotions. However, there are some emotions all people have regardless of cultures and languages such as joy, fear, angry, and sadness. Therefore, while analyzing emotions and classifying them, commonsense emotion should be selected or common model should be used. Today, many researchers prefer to use two-dimensional model owing to less complexity. There are two fixed perpendicular directed lines in this model. Horizontal axis shows valence and vertical axis shows arousal. Emotions are specified by their position in this model. High arousal refers to the excitement and low arousal refers to calmness. Valence is used as a measure of satisfaction such that low value represents sadness and high value represents happiness.
LabVIEW has two parts, the front panel and the block diagram. Block diagram corresponds to code writing part of text-based programming languages. The front panel is part of the program that was taken out. The program that is developed was created with links of graphical tools instead of writing code. Figure 2a shows the front panel and Fig. 2b shows the block diagram of the program.
Graphical user interface has been created in LabVIEW 15.0 version. FFT, wavelet transform, biomedical toolkit, and advanced signal processing toolkit of LabVIEW platform have been employed to analyze EEG signal.
Recorded EEG signal is contaminated by noises and artifacts. These noises must be suppressed in order to get correct required information from the signal and prepare the signal for further processing. Therefore, the data were band-pass filtered between 0.1 and 60 Hz.
In this study, multi-resolution decomposition of a signal was employed. Multi-resolution analysis allows to view signals at different frequencies with different resolution. The procedure for multi-resolution decomposition of four levels of signals is shown in Fig. 3. Multi-resolution was obtained by filter banks. H(n) represents high pass filter and G(n) represents low pass filter. Thus, the signal is divided into low- and high-frequency components. d1[n], d2[n], d3[n], and d4[n] represent detailed coefficients of the x[n] signal and a4[n] represents the approximate coefficient of that signal. Figure 4 shows detailed and approximate coefficient of EEG signals. The multi-resolution analysis can be made in arbitrary level depending on the desired resolution. In this study, four-level decomposition is enough to get five frequency bands of EEG signal.
The multi-resolution analysis of dB5 (Daubechies order 5) wavelet function is used for decomposition in this study. EEG signal is divided into four levels and five frequency bands that are gamma, beta, alpha, theta, and delta. This frequency bands are considered to create features. Table 1 shows frequencies corresponding to four levels of decomposition of an EEG signal.
