Title: Correction circuit of clamp level
Inventor: CHO FUJIO
IPC: H04N19/00
Filed: 1984-10-01
Abstract: PURPOSE:To prevent color slip-off, etc., of a reproduced television signal by taking the difference between the output obtained by A/D converting a television signal and the clamp level of the fixed value and averaging the difference. CONSTITUTION:A television signal is fixed at a constant clamp level through a clamp circuit 1, given to an A/D converter 2 and digitally converted. A subtractor 3 takes the difference between the digital signal converted by the circuit 2 and the clamp level of a fixed value. Then a register 4 samples the difference at every horizontal synchronizing signal, and takes out the digital output of the synchronizing signal component of the television signal. Moreover, an averaging circuit 5 averages the digital output, and an adder 6 adds the difference between averaged clamp levels to the digital signal of the circuit 2. The digital signal finally obtained in the adder 6 is more stable with less fluctuation of the clamp level than that obtained in the circuit 2.

Title: Amplifier
Inventor: INOUE MASAAKI
IPC: H03G3/30
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To provide the amplifier having a small size and high dynamic output by providing an amplitude restriction function operating with time delay on an input signal with continuous large amplitude and suppressing heat generation while the maximum output of an amplifier is secured for instantaneous and excessive amplitude. SOLUTION: The voltage of a capacitor C1 rises, the output of an operational amplifier Q3 drops and the output of an operational amplifier Q3' rises against the continuous large amplitude input signal. The inverse voltage of diodes D1 and D2 drops and the diodes D1 and D2 are conducted at the peak of the input of a main amplifier 1 and amplitude is restricted. On the other hand, the circuit does not operate owing to delay by a time constant decided by the synthesis impedance of resistors R7 and R8 and the capacitor C1 against the instantaneous large input. Thus, it operates as an amplitude restriction circuit having time delay. Thus, the amplifier having small and high dynamic output can be provided.

Filed: 1988-08-20
Abstract: PURPOSE:To obtain an excellent linearity and a low noise characteristic by varying the overall gain of plural variable attenuators when an input level is fluctuated. CONSTITUTION:When the level of an input signal Sin is going to be a high level and the level of an output signal Sout reaches a prescribed level or above, the circuit applies the control in such a way that the added attenuation of a 1st variable attenuator 4 at the pre-stage is increased by a control signal C1 after the attenuation of the 2nd variable attenuator 8 of the post-stage by a control signal C2 reaches a sufficiently large value. Moreover, when the level of the input signal Sin is low and the level of the output signal Sout reaches a prescribed level or below, first the attenuation of the 1st variable attenuator 4 of the pre-stage is sufficiently decreased by the control signal C1 and the attenuation of the 2nd variable attenuator 8 of the post-stage is decreased by the control signal C2. Thus, the linearity of amplification is kept when the level of an input signal is high and excellent noise index of the low noise amplifier is kept when the level of the input signal is low.
