WebNov 24, 2024 · Using basic C code we can create an implementation of our 8 tap single-rate asymmetric FIR filter. Note 1: This is a very basic implementation which does not do any saturation of the output data. Note 2: In the example attached to this article, the FIR filter is configured to process 256 samples (NUM_SAMPLES = 256). WebDec 15, 2024 · The output sample rate of the final FIR filter remains at 48kHz. We’ve reduced the number of multiplications by ~20%. That’s good, but it’s not spectacular. However, that’s because the overall decimation ratio is relatively small. We can see that the number of multiplication needs for the final FIR filter is almost 50% of what it used to be.
