Matlab Spectra Plot : Convolution with Low-Pass Filter
Not what you're looking for?
Lpf = ones(1,10);
y=abs(fft([lpf zeros(1,246)]));
Create a signal consisting of a 500 and 1000Hz cosine sampled t 10kHz.
fs= 10e3;
t =(0:1:0.02*fs);
f1=500;
f2=1000;
s=cos(2*pi*t*f1/fs)+cos(2*pi*t*f2/fs);
Plot the convolution of the signal with lpf, from the command filtered=conv(s,lpf)
**Plot the magnitude of the spectra of the pre and post filtered signals. Explain your results in terms of the spectrum of the signals and of the filter**
**This is the part I need help with.
