Complex DC Input Entry

Click here to return to the sources page

The Complex DC Input Block allows you to generate a DC complex signal in the block processing domain.

The block's controls allow the DC value and the format to be set. There are 32 available bits which can be used to represent decimal values.

Please make sure block Size for the complex DC module is double the size of Non-Complex inputs


Output Pins

NameFormat [int/dec] - [control/audio]Function Description
Pin 0: Output Signal Decimal - DC output signal

GUI Controls

GUI Control NameDefault ValueRangeFunction Description
Real 1 0 - (Depends on the format select)This control gives the DC real value
