How to measure group delay
Did you know?
WebThe group delay of a filter is a measure of the average time delay of the filter as a function of frequency. The group delay is defined as the negative first derivative of the filter's phase response. If the complex frequency response of a filter is H (e j ω), then the group delay is. τ g (ω) =-d θ (ω) d ω,. where θ (ω) is the phase, or argument, of H (e j ω).

WebGroup Delay measurements with Signal and Spectrum Analyzers. Phase distortions in a transmission channel are determined using group delay measurements, they must be as low as possible to maintain good signal quality. Vector network analyzers are normally used to characterize the group delay variations as a measure of phase distortion. Web16th Dec, 2015. Marcelo B. Perotoni.

A further source of puzzlement is the fact that some filters have bands of negative group delay. If we insist on the idea that the group delay is a measure of, well, delay, then negative group delay would imply that a signal can exit an electronic circuit before it enters it. Hmm. dr d\u0027invernoWebGroup delay can be construed as a measurement of how long it takes a signal to traverse a network, or its transit time. It is a proportional to the length of the network, and usually a weak function of frequency.
