polyphase_decimation
Apply a FIR filter and decimate the output, using an efficient polyphase structure
Calling sequence
y = polyphase_decimation(x,h,R)
y = polyphase_decimation(x,h,R)
Parameters
- x:
input signal (1d vector)
- h:
FIR filter coefficients (1d vector)
- R:
number of polyphase branches e.g. decimation ratio
- y:
filtered and decimated output
input signal (1d vector)
FIR filter coefficients (1d vector)
number of polyphase branches e.g. decimation ratio
filtered and decimated output
