Learning Experience : FIR Filter Design Using Windowing Method

In this experiment a digital FIR filter is designed using Windowing method.for this we had required 5 parameters namely, Attenuation in both pass and stop bands in dB, pass band and stop band frequency and Sampling frequency are taken as input.In this experiment we implemented Step 1 hd(s) and step 2 hd(n).while other group implemented step 3 h(n). and then we combined this two function to form a complete program. I learnt that ripples in pass band are less in hamming as compared to rectangular and hanning and also hamming has a linear phase than rectangular and hanning.
