WebQuestion: We want to design a low-pass FIR filter with a passband frequency of fpass =0.12 and a stopband frequency of fstop =0.28. We want a maximum of +/−1 dB of change in the passband and at least 40 dB of attenuation in the stopband. a. (1 pt) Determine the cut-off frequency of the filter. WebMar 31, 2005 · Because their frequency-magnitude-response envelopes are sin(x)/x-like, CIC filters are typically either followed or preceded by higher performance linear-phase lowpass tapped-delay-line FIR filters whose tasks are to compensate for the CIC filter's non-flat passband.That cascaded-filter architecture has valuable benefits. For example, …

When we approximate an ideal filter with a practical filter using the window method, we accept some approximation error. The peak approximation error depends on the window type and is known for each window as reported in Table I.

Web$\begingroup$ Once you have the coefficients from a filter design, (b for FIR b and a for IIR) you can used a couple different functions to perform the filtering: lfilter, convolve, filtfilt. Typically all these functions operate similar: y = filtfilt(b,a,x) If you have a FIR filter simply set a=1, x is the input signal, b is the FIR coefficients.
