For example, changing the frequency from 32.768Mhz to 2kHz there is a scale down of 16384.
From the algorithms I've seen you have to discard 16384-1 samples and only count the 16384th sample. However, that many samples being lost will lose important parts of the information. How does decimation work then?
A signal is sampled at 2kHz and then modulated with a carrier wave of signal frequency 8.192MHz which is sampled at 32.768MHz. I am trying to revert it back to 2kHz, by decimation. I assume pass it through a LPF and apply decimation however, the points sampled at 32.768MHz are then lost?
