Downsampling fir filter
WebTo implement the filtering part, you can use either FIR or IIR filters. To implement the downsampling part (by a downsampling factor of “M”) simply keep every Mth sample, … WebUpsampling requires a lowpass filter after increasing the data rate, and downsampling requires a lowpass filter before decimation. Therefore, both operations can be accomplished by a single filter with the lower of the two cutoff frequencies.

WebThe Raised Cosine Receive Filter block filters the input signal using a normal raised cosine FIR filter or a square root raised cosine FIR filter. It also downsamples the filtered signal if you set the Output mode parameter to Downsampling. The FIR Decimation block implements this functionality.

WebNov 26, 2024 · Your option 1. has nothing to do with brute force: that's just downsampling without filtering, leading to complete aliasing, and is practically never a sensible option, unless you really don't care about aliasing. 3.: no, resample doesn't truncate the FFT, that'd be a very bad resampler, and should almost never be done.
