摘要： A detector for a modulated AM stereophonic signal of simple configuration in which the sub signal of the stereophonic signal is detected accurately independent of fluctuations in the frequency of the carrier signal. In the detector circuit, the output phase of a VCO in a PLL circuit which is fed with an amplitude limited signal corresponding to the output of an IF amplifier in the receiver is controlled by a variable phase shifter that performs phase shifting according to a control voltage. The phase-controlled output is used as a synchronous detection signal for sub signal detection. The control voltage is produced to correspond to the phase difference between the phase-controlled signal and the carrier signal of the received AM stereophonic signal.

摘要： An AM detector circuit capable of performing an AGC function having a wide dynamic range and low level of distortion and spurious interference. A first differential amplifier receives an amplitude-modulated signal to be detected as differential inputs. Outputs of the first differential amplifier are connected as constant current source inputs to second and third differential amplifiers. The differential inputs of the second and third differential amplifiers are fed with a signal synchronous with the carrier wave of the amplitude-modulated signal. Outputs of the second and third differential amplifiers are interconnected to provide multiplication outputs representing the product of the amplitude-modulated signal and its carrier wave. The detector AM signal is passed through a low-pass filter and then through a fourth differential amplifier to a current mirror circuit. The current mirror circuit feeds parallel-connected transistors of opposite conductivity types connected across the differential input of the first differential amplifier to provide the AGC function.

摘要： A muting circuit for an AM stereophonic receiver of the type in which a received signal is phase modulated with a sub signal and amplitude modulated with a main signal and in which noise generated under certain adverse conditions is eliminated. A first detection signal is generated when the level of a received AM stereophonic signal is lower than a predetermined value, a second detection signal is generated upon detection of a non-locked state of a phase-locked loop circuit used to detect the sub signal, a third detection signal is generated when a frequency deviation detection senses is that a free-running frequency of a voltage controlled oscillator in the phase-locked loop circuit and a frequency of the AM stereophonic signal are different in frequency by more than a predetermined value; and a fourth detection signal is generated when a stereo pilot signal is absent. A muting circuit is activated in response to any of first through fourth detection signals. The frequency deviation detector is preferably implemented as a window detector which has an input-output characteristic including hysteresis.

摘要： In a current-controlled type division circuit, an auxiliary transistor is employed in conjunction with a division control transistor to allow a divisor signal, which normally flows through the division control circuit, to flow through the auxiliary transistor in the case when a division controlling signal applied to the base of the division control transistor falls below a predetermined level. By the provision of the auxiliary transistor, the divisor signal of a predetermined minimum is adapted to be flown therethrough to prevent the gain of the division circuit from exceeding a predetermined maximum.
