Receiver using receiving condition signal for correcting influence of the reception band width

摘要

For realizing a correct measurement of a receiving condition even if the bandwidth of intermediate frequency amplification is narrow, the gain of a variable gain amplitude detector circuit is controlled by an output signal of a function generator circuit so as to cancel the bandwidth characteristic of an intermediate frequency amplifier circuit, to flatten the total bandwidth characteristic of a circuit for detecting an amplitude value of a received signal, thereby eliminating the influence of angle modulation related components in the received signal or desired wave.
