In Code 6.1, there is a decimation of 4 in the receiver matched filter. Why is that so? Changing it to 1, I get the following animation, which looks the same to me as using decimation of 4 (except it slower). What is the purpose of the decimation?
Also, why does decimation=1 result in a slower change than decimation=4? I was expecting it to be the same since tau is a fraction of a symbol period
Decimation = 1 is above ^ . Decimation = 4 is below v .

The Tx RRC filter always interpolates by SamplesPerSymbol but the RRC only decimates by the supplied Decimation factor. The remaining symbols (SamplesPerSymbol - Decimation) can be used to better estimate the timing error. This is likely slower since you are processing 4x the data when setting decimation to 1.
