DCSourceControlFract32

Discussion

THIS MODULE IS DEPRECATED AND NOT RECOMMENDED FOR NEW DESIGNS. PLEASE USE THE UPDATED DCSourceV2Fract32 MODULE INSTEAD.

The DC source control module has an internal variable holding one data value. The module continuously fills the output wire with the internal data value multiplied by the value of the input control signal. The output has the same number of channels as the input. The output blockSize and sample rate can be specified. If not specified, the values are taken from the system input.

Matlab Usage

File Name: dc_source_control_fract32_module.m 
 M=dc_source_control_fract32_module(NAME, BLOCKSIZE, SAMPLERATE) 
 Creates a DC source that takes on the value of the input control signal  
 multiplied by the scaler variable value 

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