MATLAB Usage
File Name: pink_noise_subsystem.m
SYS=pink_noise_subsystem(NAME, SR, NUMCHANNELS, BLOCKSIZE)
Creates a module which outputs pink noise at a specified standard
deviation. Internally, the module uses a white noise generator
followed by an IIR filter. Arguments:
NAME - name of the module.
SR - sample rate. This must be set since this is an output module.
NUMCHANNELS - number of interleaved channels in each output pin.
BLOCKSIZE - number of samples per output channel.
