Using the Matlab commands fir1 and freqz, construct a FIR digital bandpass filter with cut-off frequencies of 150 and 300 Hz for a signal with a sampling frequency of 1000 Hz and 512 sampled points. Let the order of the filter be 10, and then increase it to 20 and then 40. The freqz command will plot the amplitude and phase response; how does increasing the filter order change the filter?
