摘要： A voltage/current conversion circuit giving an output current which is proportional to an input voltage. The circuit includes an operational amplifier to one input of which the input voltage is applied, first and second transistors, to the commonly connected bases of which the output of the operational amplifier is applied, and a feed-back path connecting the collector of the first transistor to the other input of the operational amplifier.

摘要： An AM stereophonic receiver including a stereophonic pilot signal eliminating circuit which substantially completely eliminates a pilot signal in an input stage of a matrix detector. A received AM stereophonic signal, of the type in which the carrier signal is phase-modulated with a sub-signal and amplitude modulated by a main signal, is coupled to a main signal detector and a sub-signal detector. The output of the sub-signal detector is coupled through a band amplifier which produces as an output a signal corresponding to the pilot signal contained in the stereophonic signal. The outputs of the sub-signal detector and main signal detector are coupled to inputs of adder/subtractor circuit in a matrix detector while the output of the band amplifier is also coupled thereto in a phase so as to cancel the pilot signal contained in the output of the sub-signal detector.

摘要： A phase control circuit for use in a compatible quadrature AM stereophonic receiver in which the phase of the output signal of a voltage-controlled oscillator in a phase-locked loop circuit has a fixed predetermined phase difference with respect to the input signal at all times. A variable phase shifter varies the phase of the output signal from the voltage controlled oscillator in the phase-locked loop circuit in accordance with an input control voltage. The phase of the output of the variable phase shifter is compared with the phase of the input intermediate frequency signal to produce a control signal voltage for the variable phase shifter which varies according to the phase difference between the two compared signals wherein the desired signal having a fixed phase difference is provided at the output of the variable phase shifter.
