摘要： An apparatus for receiving broadcast FM waves using an FM (Frequency Modulated) detector is disclosed in which an output signal level of an automatic gain controller (AGC) is controllable so that when the C/N ratio is reduced and the output level of the automatic gain controller is reduced, the loop gain of a PLL type FM demodulator is accordingly reduced and response is delayed with the bandwidth being narrowed . Therefore, since delayed threshold extension is applied thereby, no signal noise, such as white points appearing on an image screen, will occur.

摘要： This invention pertains to a method of correcting a position of a disk record on a turntable for positioning the record on the turntable in a concentric manner relative to the rotational center of the turntable.In the method of the invention, a stylus which is mounted on a pickup arm traces a groove of a record placed on a turntable. On tracing the groove of the record, an angular displacement of the pickup arm is detected for detecting an eccentricity of the record relative to the rotational center of the turntable. The position of the record on the turntable is corrected in accordance with the detected eccentricity.

摘要： This invention relates to a volume control for an audio apparatus and more particularly to a fader for fading in or out a level of an audio signal. The volume control of the invention comprises a charge and discharge circuit having a capacitor charged and discharged by a constant current in response to a fade-in or fade out operation, and a function generator to generate a signal having a logarithmic waveform periodically repeated. A control signal generator compares the voltage across the capacitor of the charge and discharge circuit with the logarithmic waveform signal from the function generator to generate a control signal logarithmically varying in accordance with variation in the voltage across the capacitor of the charge and discharge circuit. An impedance controller logarithmically changes an impedance of an audio signal line in accordance with the control signal to logarithmically change the level of the audio signal in substance.

摘要： This invention relates to a playback system for a magnetic tape recorder comprising an amplitude distortion corrector. It has an input versus output characteristic such that when the input level is less than the playback saturation level, which corresponds to the start of non-linear characteristics of the playback signal produced from a recorded signal at more than the recording saturation level due to a saturation of the magnetic tape, the output level is proportional to the input level. When the input level is more than the playback saturation level, the input verses output characteristics is complementary to the input versus output characteristic of the magnetic tape at corresponding signal levels. The playback system further comprises a high frequency emphasizer having an emphasizing circuit section having predetermined frequency characteristics disposed before the amplitude distortion corrector to emphasize predetermined frequencies in the playback signal so as to correct frequency dependent variations in the non-linear characteristics of the playback signal corresponding to a high level recorded signal which occurs due to saturation of the magnetic tape. The playback system further comprises a high frequency attenuator disposed after the amplitude distortion corrector and having frequency characteristic complementary to that of the high frequencies emphasizer so as to attenuate the frequency emphasized by the high frequency emphasizer.
