Title: Switched capacitor circuit
Inventor: AKUTSU EISAKU
IPC: H03H19/00
Filed: 1983-09-30
Abstract: PURPOSE:To obtain the circuit constitution where the amplification factor is varied continuously by using a varactor element as a capacitive element of a switched capacitor circuit. CONSTITUTION:The capacitance between the anode and cathode is decreased in a varactor diode C44 when the reverse voltage is increased. Thus, a signal controlled by a switch S42 allows the diode C44 to act like a coupling capacitor separating the signal from a control voltage and a resistor R44 prevents this signal from being leaked to a control voltage input terminal CT4. When a prescribed control voltage is applied from this terminal CT4, the diode C44 acts like a capacitor with a prescribed capacitance value. Thus, the capacitance value controlled by the switch S42 is a combined capacitance value of series connection between a capacitor C43 and the diode C44. Thus, in changing continuously the control voltage, since the diode C44 is also changed continuously, the coefficient is changed continuously.

Title: Fm demodulation circuit
Inventor: HONJO MASAHIRO
IPC: G11B20/06
Filed: 1987-07-21
Abstract: PURPOSE:To prevent the deterioration in picture quality due to moire by subtracting an arithmetic signal obtained by operating a lower side band component of an FM signal and a carrier frequency component of the FM signal from the FM signal and applying FM demodulation so as to prevent an undesired component from being generated in a demodulation signal. CONSTITUTION:In modulating an FM carrier frequency fc by a signal fs, a 1st low side band f1=fc-fs and a 2nd low side band f2=fc-2fs or the like are generated. The undesired component fm=2fc-2fs after the demodulation is considered to be the demodulation of the 2nd side band component. Then the level of the 2nd side band component is changed just before the demodulator or eliminated. For example, the undesired side band component is operated from the FM signal coming from the terminal 1 by an arithmetic circuit 3 and it is subtracted from the input FM signal by the subtractor 2. The FM signal from which the undesired component is eliminated is demodulated by a demodulator 4 to obtain a demodulation signal without moire, which is outputted to a terminal 27.
