This is a convenience wrapper for calling firdes.root_raised_cosine(). A root-raised-cosine (RRC) filter is one of the most common pulse shaping filters in digital communications systems, used to perform matched filtering. See [1](RRC filter at wikipedia) for more info on RRC filtering.
Parameters
- Gain
- Scaling factor applied to output.
- Sample Rate
- Input sample rate in Hz.
- Symbol Rate
- Input symbol rate in Hz, NOT samples per symbol.
- Excess BW
- The filter parameter, sometimes called roll-off factor or beta, between 0 and 1. A higher value means more bandwidth is being used. A common value is 0.35.
- Num Taps
- Number of taps for the generated filter to have
