Filter Data
Filter Data
Create and filter data using the FFT to perform fast convolution of the FIR filter coefficents and the input series.


Cross Correlation
Cross Correlation
The cross-correlation is used to determine how similar two series are to each other. XCORR performs correlation by computing the direct convolution of the input series.


Curve Fitting
Curve Fitting
Curve fitting performs a Least Squares Polynomial fit.


Copy & Paste From Excel
Copy/Paste from Excel
Copy and paste data straight from Excel. Include header information to keep track of channel names, channel units, etc.


Read an ASCII File
Read ASCII File
Reads an ASCII file with multiple columns of data and returns a series or table.


Specgram
Specgram
The SPECTRUM function displays the frequency content of the data where the SPECGRAM function displays the frequencies and the times at which those frequencies occurs.


Spectrum
Spectrum
Returns the normalized magnitude of the FFT. The SPECTRUM is normalized so that a sinewave of amplitude A and frequency F yields a SPECTRUM of amplitude A at frequency F.


Generate Sine Wave
Generate Sine Wave
Generate a sinewave with added noise.


Single Pole Low Pass Filter
Single Pole Low Pass Filter
Emulates a single pole analog low pass filter. The single pole analog lowpass filter is implemented in the digital domain using the impulse invariant technique.
