  2. Group delay and phase delay - Wikipedia

    en.wikipedia.org/wiki/Group_delay_and_phase_delay

    The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.

  3. Butterworth filter - Wikipedia

    en.wikipedia.org/wiki/Butterworth_filter

    Gain and group delay of the third-order Butterworth filter with = The group delay is defined as the negative derivative of the phase shift with respect to angular frequency and is a measure of the distortion in the signal introduced by phase differences for different frequencies. The gain and the delay for this filter are plotted in the graph ...

  4. Bessel filter - Wikipedia

    en.wikipedia.org/wiki/Bessel_filter

    The Taylor series expansion of the group delay is = + +. Note that the two terms in and are zero, resulting in a very flat group delay at =. This is the greatest number of terms that can be set to zero, since there are a total of four coefficients in the third-order Bessel polynomial, requiring four equations in order to be defined.

  5. Lattice delay network - Wikipedia

    en.wikipedia.org/wiki/Lattice_delay_network

    An ideal delay line characteristic has constant attenuation and linear phase variation, with frequency, i.e. it can be expressed by =where τ is the required delay.. As shown in lattice networks, the series arms of the lattice, za, are given by

    4) Group delay, as mentioned by others on this talk page is quite complicated in concept. For example, it cannot give any difinitive or quantifiable information outside the context of modulation and demodulation. And group delay cannot even give the time delay of the DUT frequency components.

  9. Chebyshev filter - Wikipedia

    en.wikipedia.org/wiki/Chebyshev_filter

    Gain and group delay of a fifth-order type II Chebyshev filter with ε = 0.1. The gain and the group delay for a fifth-order type II Chebyshev filter with ε=0.1 are plotted in the graph on the left. It can be seen that there are ripples in the gain in the stopband but not in the pass band.
