Abstract
A superheterodyne receiver is provided in which first and second envelope detectors having a function of regulating the gain and offset voltage are used to detect receive signal levels from first and second intermediate frequency signals. These receive signal levels are compensated with respect to a phase difference through a phase difference compensating circuit. The compensated signals are then summed by an adder to provide a receive signal level detection output.
