A decimation operation can also be used at this stage as an argument of Frequency Xlating FIR Filter to operate only at a minimum number of samples dictated by the sampling theorem. However I am not decimating the signal here since my objective is to display the proper waveforms for which ...
The Frequency Xlating FIR Filter block filters the signal according to the parameters listed in the Low-Pass Filter Taps block. Next, the signal is demodulated by the FM Demod block and scaled according to the variablegain_scaby the Multiply Constant block. (The “gain” option in the FM D...
