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.
