Envelope detector consists of
Explanation: An envelope detector consists of a rectifier and a low pass filter. The detectors are matched to the envelopes and not to the signal themselves.

The correlating detector is also known as
Explanation: Coherent detector considers phase as the most important parameter. This coherent detector is also known as maximum likelihood detector.

The minimum required spacing is the difference between the
Explanation: The frequency difference between the center of the spectral main lobe and the first zero crossing is called as the minimum required spacing in non coherent detection.
