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.

(inner) SignalProcessing
Construct an instance of a Signal object type. This should be instantiated in your JavaScript code as
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.
