WebAug 2, 2024 · 1. Step method: In this method, by performing pattern synthesis of optimal array, the designing of array weights is done and using this approach, FIR filter is designed. 2. Joint optimization method: In it, the frequency and spatial response are optimized jointly for designing the FIR filter. WebThe phase delay and group delay of linear phase FIR filters are equal and constant over the frequency band. For an order n linear phase FIR filter, the group delay is n/2, and the filtered signal is simply delayed by n/2 time steps (and the magnitude of its Fourier transform is scaled by the filter's magnitude response).This property preserves the wave shape of …
