DCSource

Discussion

THIS MODULE IS DEPRECATED AND NOT RECOMMENDED FOR NEW DESIGNS. PLEASE USE THE DCSourceV2 MODULE INSTEAD.

The DC source module has an internal variable holding one data value. The module continuously fills the output wire with the internal data value. Since this is a source module, you must specify the number of channels, blockSize, and sample rate of the output pin.

Matlab Usage

File Name: dc_source_module.m 
 M=dc_source_module(NAME, NUMCHANNELS, BLOCKSIZE, SAMPLERATE) 
 Creates a source module that allows you to inject DC test data into 
 the audio processing layout. 

 Arguments: 
    NAME - name of the module. 
    NUMCHANNELS - number of interleaved channels in each output pin. 
    BLOCKSIZE - number of samples per output channel. 
    SAMPLERATE - sample rate of the output signal, in Hz.
