1) FILTER DESIGN

FIR:
-fir1* (f'=2f)
-fir2*
-firpm
-firls

IIR:
-butter
-cheby1
-cheby2
-ellip
-yulewalk

2) FILTER ANALYSIS

FIR:
-freqz
-fft*

IIR:
-freqz

3) APPLY FILTER

FIR:
filter
fftfilt
convolve

IIR:
filter

4) DATA ANALYSIS
We want to compute power spectral density (PSD)

pwelch(x,window,noverlap,nfft,Fs)
pwelch(x,[],[],[],Fs)

On a free day, consult: "help spectrum"
