Title: Muting circuit of am stereo receiver
Inventor: NISHIOKA AKIRA
IPC: H03G3/34
Filed: 1980-02-06
Abstract: PURPOSE: To suppress the noise occurrence when the output that gives a wave detection to the subsignal exceeds a prescribed level, by generating a muting signal to attenuate the output of the subsignal with this signal.  
     CONSTITUTION: The subsignal is detected through the quadrature FM wave detector 2 and the integrator 3 for the intermediate frequency signal IF received a phase modulation by the subsignal. This subsignal is delivered through the buffer circuit 5, and the output of wave detection is applied to the smoothing circuit 9 via the HPF6, the wind comparator 8 plus the diodes D 1  and D 2 . Then the transistor Q 1  is turned on when the level of the wavedetection output exceeds a prescribed value, and the wave detection output is attenuated. As a result, the noise can be eliminated in case the phase modulation caused by a radio interference is large.

Title: Differential amplifier
Inventor: ITO YASUHIRO
IPC: H03F3/45
Filed: 1986-01-24
Abstract: PURPOSE:To reduce distortion at the time of a large amplitude by providing two auxiliary differential amplifiers and compensating a decrease in amplifying operation when there is an input signal with a large negative amplitude. CONSTITUTION:In the 1st auxiliary differential amplifier, when signal voltages of signal sources 13 and 14 are zero, the base voltage of the transistor (TR) 23 of the 1st auxiliary differential amplifier is VB3+VB4 lower than the base voltage of the TR 24. In the 2nd differential amplifiers including TRs 25 and 26, the TR 25 corresponds to the TR 24 and the TR 26 corresponds to the TR 23 respectively; and they do not operate to a small signal voltage ES. When the signal voltage ES becomes large in a negative direction, the 2nd auxiliary differential amplifier operates to remove waveform distortion.
