Dear all, i am working on a design project and still stuck at this problem. i will appreciate any help! =)

Design a digital FIR low pass filter with the following specifications
ωp = 0.2π Rp = 0.25 dB, ωs = 0.25π As = 60 dB,
(a)
By using hamming window and matlab function firl, find the impulse response and provide a plot of the frequency response of the designed filter.
(b)
Redesign the above filter by using the matlab function Remez (or firpm) and provide a plot of the frequency response of the designed filter.
(c)
Compare and explain any differences between the two filter designs.

You posted just after midnight in the part of North America where most
of the population lives. Who _exactly_ were you expecting would be
sitting right by their computer ready to give you a detailed tutorial
on signal processing and have the answer ready for you only 50 minutes
after you posted?

And when I say "Who _exactly_", I mean that you should name names. You
expected answers on four detailed signal processing questions and you
expected the answer quickly. Name the _specific_ individuals you
expected would provide you with those answers at this time of day, on
such short notice.

Well, you'll just have to toughen up if you expect to make it in this
field.
