WebDec 1, 2002 · A finite impulse response (FIR) filter is a filter structure that can be used to implement almost any sort of frequency response digitally. An FIR filter is usually … WebFeb 2, 2006 · Introduction ¶ This program designs an FIR filter, given a desired frequency response H des ( ω) . The design is judged by the maximum absolute error (Chebychev norm). This is a convex problem (after sampling it can be formulated as an SOCP), which may be written in the form: minimize max H ( ω) − H des ( ω) for 0 ≤ ω ≤ π,

The convex optimization criterion is given by Minimize ‖ ( )‖ or ‖ ( )‖ Subject to ‖ ( )‖=1. I use CVX to design a filter to achieve optimization. I set the number of samples is N=50. So there are 50 samples, and the desired frequency is 2000Hz.
