Signalstärkeanzeige eines Empfängers |
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 (116, 16) is controlled by an output signal of a function generator circuit (110, 410, 610, 710, 810) so as to cancel the bandwidth characteristic of an intermediate frequency amplifier circuit (13), to make flat the total bandwidth characteristic of a circuit (17, 18, 19) 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. <IMAGE> |
