Hello,
I am trying to prefilter an error message via a lowpass filter which is then fed in to a Adaptive Filter which should cancel out the error signal.
The issue I have at the moment is that the filtered signal from the lowpass filter is not being filtering out by the Adaptive Filter.
The 20s Noise signal is ought to be filtered by the lowpass filter. It is White noise which is sampled at 44100 Hz and has a noise amplitude of 0.5.
Meanwhile the sine signal has a sampling fq of 44100, a frequency of 1kHz and an amplitude of 0.5.
The program works if I remove the FIR Filter but I want to prefilter the noise signal. I also tried using an IIR Filter but that was also unsuccessful.
I would be grateful for any input on my situation.
Thanks
