Design a linear phase low pass filter

Click For Summary

Homework Help Overview

The discussion revolves around the design of a linear phase low pass filter with specific performance criteria, including passband tolerance, cutoff frequency, and rejection band requirements. The subject area is digital signal processing (DSP).

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants inquire about the specifics of the design process, including whether to use operational amplifiers or digital signal processing techniques. Questions are raised regarding the resources and knowledge the original poster has regarding filter design.

Discussion Status

The discussion has prompted participants to seek clarification on the original poster's background and resources related to DSP. Some guidance has been offered regarding the implications of the passband accuracy on the polynomial choice for filter design. The thread is currently locked.

Contextual Notes

There is a lack of detailed information from the original poster about their course or the context of the assignment, which has led to questions about the nature of the task and the resources being utilized.

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?
