WebQuasi-Linear Phase Halfband IIR Designs The drawback of IIR designs is their nonlinear phase, which may cause distortion. This can be largely mitigated by compensating for the nonlinear phase. It is possible to achieve almost linear phase response using specialized IIR design algorithms.

WebDec 15, 2024 · According to Wikipedia , “a half-band filter is a low-pass filter that reduces the maximum bandwidth of sampled data by a factor of 2 (one octave).” When we start out with a sample rate Fs, the bandwidth of that signal goes from 0 to Fs/2. A half-band filter is used to reduce the bandwidth to Fs/4. WebFeb 2, 2011 · The modulator input is 20Khz sinus signal. And this signal is oversampled to 2.5Mhz. So decimation ratio is about 64. First I designed a CIC filter which has a decimation ratio of 16. After a halfband filter and an FIR filter. So halfband filter output is 80 Khz, FIR filter output is 40 khz.

WebJan 20, 2024 · A FIR filter is a linear digital filter with a finite impulse response and whose z-transform has only nulls. Such a filter is unrealizable in analog technology, which makes it unique in the digital field. The advantage of the FIR filter is always stable and easy to implement with a linear phase response. Referring to WebThis MATLAB function designs a lowpass FIR halfband filter of order n with an equiripple characteristic.
