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 PLL tuning device in a receiver uses a digital memory board and array of photo-transistors scanning the memory board for station selection. When the transistors are lined up with a column, a digital output is fed to a switching device and to a programmable frequency divider. Muting action is released when the output is delivered to the divider, but, when the array is between columns, muting action takes place. In one embodiment, the photo-transistor output is fed to a latch and to an OR gate serving as the switch. A one-shot is triggered in response to the setting of the OR gate at an H level. Digital information is fed to the programmable frequency divider from the latch until the one-shot is fired. In another embodiment, the latch and one-shot are eliminated. Photo-transistor output is fed to both an OR gate and the frequency divider. The OR gate controls a switch that closes muting switches only when information is being generated by the photo-transistors. However, when the sensor array is between signals the tuner is maintained in a muted state.
