Index Selectable Demultiplexer
Description
The Index Selectable Demultiplexer block allows route an input to one of many possible output pins. The output is selected based on a control signal value, in 32.0 integer format from an Index Lookup Table, RMS Table, or DC Input block.
Index Selectable Demux (SW Slew) block allows smooth transition when switch outputs.
Variants
- Index Selectable Demux (Mono)
- Index Selectable Demux (Stereo)
- Index Selectable Demux (SW Slew)
