Module to access some signal processing methods.
The static methods defined in ptolemy.math.SignalProcessing are targeted. This module is under development. Only the FFT method has been implemented.
var dsp = require("dsp"); var dspEngine = new dsp.Signal();An instance of this object type implements the following functions:
- fft(signal): Return an object containing the real and imaginary parts of the Fast Fourier Transform ( FFT) of the input.
- (TODO) ifft(coef): Return an object containing the real and imaginary parts of the inverse FFT of the input sequence.
