How do you measure group delay?

There are two primary means of measuring group delay. The most widely used involves frequency domain method converting small-signal S-parameters to group delay. The time-domain method directly measures the time that a pulse takes to move through a network.

How do you calculate group delay and phase delay?

Use the grpdelay function to compute group delay of a filter. For example, verify that, for a linear-phase FIR filter, the group delay is one-half the filter order. The phase delay of a filter is defined as the negative of the phase divided by the frequency: τ p ( ω ) = - θ ( ω ) ω .

How do you calculate group delay in antenna?

The group delay of the antenna is calculated approximately by taking the frequency derivative of the input impedance phase function. In actuality, the group delay of the antenna is composed of the contribution from two constituents – the input impedance and the far-field phase.
