- property sdr.Decimator.polyphase_taps : ndarray
The polyphase feedforward taps
.Notes¶
The prototype feedforward taps
are the feedforward taps of the FIR filter before polyphase decomposition. The polyphase feedforward taps are the feedforward taps of the FIR filter after polyphase decomposition.The polyphase feedforward taps
are related to the prototype feedforward taps byExamples¶
