WebJul 2, 2004 · A properly designed FIR filter is an example of a linear phase filter. If some groups of frequencies experience a different delay from others (called group-delay error), it will color the sound or cause audible artifacts. A filter that experiences group-delay errors cannot be phase linear. WebAug 11, 2024 · Digital filter is an important fundamental component in digital signal processing (DSP) systems such as image processing [], speech signal processing, and communication systems [].In particular, the finite impulse response (FIR) filter is one of the basic and most commonly used digital filters due to its linear phase feature.

WebFIR filters are usually designed to be linear-phase (but they don’t have to be.) A FIR filter is linear-phase if (and only if) its coefficients are symmetrical around the center coefficient, that is, the first coefficient is the same as the last; the second is the same as the next-to-last, etc. WebJun 3, 2024 · Linear-Phase Filters (Symmetric Impulse Responses) A linear-phase filter is typically used when a causal filter is needed to modify a signal's magnitude-spectrum while preserving the signal's time-domain waveform as much as possible. Linear-phase filters have a symmetric impulse response, e.g.,

WebJun 3, 2024 · Although the design of FIR filters with linear phase is an easy task.
