Experiment 7 - Digital FIR filter design using windowing method

In this experiment we had to design a digital filter using windowing technique and study the spectrum of the filter .

From the experiment I learnt that in the magnitude response of the FIR  filter there we ripples present in the stopband of LPF . 

For BPF and LPF  the phase response is linear and the values of Ap and As almost match
