Design a linear phase low pass filter whose specification is:


1) Maximum tolerance in the passband equal to 0.01% (linear) in the passband;


2) Cutoff frequency at ω_c = 0.3π and transition band at 0.05π;


3) Minimum reduction of the 0.95 rejection band.

Welcome to PF.

What are you supposed to do to "design" this filter? Are you supposed to use opamps? How many stages? Or are you supposed to use DSP?

What have you learned so far about filters and designing them. You were not given this assignment out of thin air, right? What class is this for?

The content is related to DSP. The statement of the question is just that, I don't have more information.

What textbook or learning resources are you using for DSP? What have you learned so far about designing digital filters? What order and which polynomial do you think you need to use for this design? (Hint: The 0.01% passband accuracy will likely dictate the polynomial choice...)

I'm using these two books:

Signals and Systems, 2a. ed., Prentice-Hall, 1996, A.V., Oppenheim, A.S. Wilsky with S.H. Nawab. Signals and Systems, 2nd Edition, 2002 Simon Haykin, Barry Van Veen.

What class is this for? Or is it for self-study?
