My previous post [1] covered lowpass IIR filter design, and provided a Matlab function to design them. Here, we’ll do the same thing for IIR bandpass filters, with a Matlab function bp_synth.m. WebJun 3, 2024 · A Linkwitz-Riley filter uses a parallel combination of low-pass and high-pass filters which results in zero gain at the crossover frequency. Because of the zero gain at the crossover frequency, a Likwitz-Riley filter behaves like an all-pass filter delivering a flat amplitude response and a smooth changing phase response.
