え取り出すようにしたことを特徴とするＡＭ受信機。From a double-sideband DSB signal having a lower sideband LSB and an upper sideband USB centered around the carrier wave, the carrier wave is detected by a lock loop PPL circuit, and the DSB signal is synchronously detected, and each of the sidebands is detected. In an AM receiver that selectively extracts and demodulates either one of the signals, the above P
A sideband selection circuit is provided that selects each sideband according to the control voltage of the voltage controlled oscillator VCO of the LL circuit, and the signal of one of the above wavebands is automatically switched in conjunction with the channel selection operation. An AM receiver characterized in that it can be taken out.
