In signal processing, linear phase is a property of a filter where the phase response of the filter is a linear function of frequency. The result is that all frequency components of the input signal are shifted in time (usually delayed) by the same constant amount (the slope of the linear function), which is referred to as the group delay. Consequently, there is no phase distortion due to the time delay of frequencies relative to one another.

The main advantage digital IIR filters have over FIR filters is their efficiency in implementation, in order to meet a specification in terms of passband, stopband, ripple, and/or roll-off. Such a set of specifications can be accomplished with a lower order (Q in the above formulae) IIR filter than would be required for an FIR filter meeting the same requirements. If implemented in a signal processor, this implies a correspondingly fewer number of calculations per time step; the compu… Web5 apr. 2024 · In this paper, a new design approach of approximately linear phase infinite impulse response (IIR) low pass digital differentiator (LPDD) is proposed and studied.

WebNon-linear phase, of course. 😉 Actually, the most popular alternative is “minimum phase”. Minimum-phase filters (which might better be called “minimum delay” filters) have less delay than linear-phase filters with the same amplitude response, at the cost of a non-linear phase characteristic, a.k.a. “phase distortion”. http://leda.elfak.ni.ac.rs/publications/pdf/Conferences/2015/Etran/On%20the%20Synthesis%20and%20Realization%20of%20Selective%20Linear%20Phase%20IIR%20Filters.pdf
