摘要： A first PIN diode is connected to the input side of a tuner at the front end of an FM receiver, in an AC coupled fashion parallel to the tuner. A correction inductance is connected parallel to the first PIN diode in an AC coupled fashion. The tuner is connected, at its output side, parallel to a series-connected circuit of a correction capacitor and a second PIN didode. The anodes of the first and second PIN diodes are supplied with an automatic gain control (AGC) voltage. When the AGC voltage varies, the resistances of the first and second PIN diodes vary in a manner to adjust the degree to which the correction inductance and the correction capacitor affect the resonance in the tuner.

摘要： A combination device having a magnetic recording and reproducing unit and an electronic tuning type receiver, where the channel presetting switches of the electronic tuning type receiver also can act as the operating switches of the magnetic recording and reproducing unit. The electronic tuning type receiver is of the type which is tuned by control signals provided to a tuning means by a plurality of channel selecting switches. A selection circuit is interposed between the tuning means and the plurality of channel selecting switches and provides the plurality of control signals to the tuning means when a selection switch is in a first binary state, and provides the plurality of control signals to a tape-control section when the selection switch is in a second binary state. The tape-control section, in response to the plurality of control signals, controls the mode of operation of the magnetic recording and reproducing unit, and also provides a signal indicating the mode of operation to a sensing circuit. The sensing circuit, in turn, provides mode signals to a digital display unit which can visually display the mode of operation when the magnetic recording and reproducing unit is being used, as well as can visually display the station frequency or the like of the selected station when the electronic tuning type receiver is being used.

摘要： The present invention is a magnetic tape running state and tape run amount display device which displays visually the running direction and speed or the run amount and direction of the magnetic tape. An up-down counter is provided with a clock input signal having a pulse generated in correspondence with the run of the tape and is also provided with a count control signal. The count control signal has an UP signal generated when the tape is being transported in a first or forward direction, and has a DOWN signal generated when the tape is being transported in a second or reverse direction. The up-down counter provides a binary output count signal to a display circuit in correspondence with the clock input signal and the count control signal. The up-down counter can also be provided with a reset input responsive to a reset signal which acts to reset the count back to logic 0. The display circuit provides a visual representation of the binary output signal, and may include a first binary-to-digital decoder and a second binary-to-digital decoder, each being responsive to a preselected portion of the binary bits provided by the up-down counter. A plurality of light emitting diodes are connected between decimal output lines of the first and second binary-to-digital decoders for providing a visual indication of the tape running state and run amount. In one arrangement, the diodes are arranged to define a line. The display circuit also can be responsive to the binary tuning signal provided by an electronic tuning type receiver.
