Hence, using envelope delay, reducing the measurement aperture reduces the group delay resolution.
This article described the measurement of group delay by a system analyser in which the tuned input of the spectrum analyzer demodulates a frequency modulated signal and measures the envelope delay through any component, assembly or subsystem.
Envelope delay measurements are also commonly made with frequency modulation (FM).
