Filed: 1989-02-10
Abstract: PURPOSE:To obviate the generation of linear distortions in a reproduction video signal at the point of the time when FM demodulation is executed by detecting the linearity and level of the demodulated reproduction video signal and controlling a clamp level and AD conversion level. CONSTITUTION:The reproduction FM signal of the video reproducing machine which reproduces the recording medium subjected to FM modulation recording by time division multiplexing of the reference signal having high, middle and low levels in the recording video signal by field periods and subjects the same to digital processing is subjected to FM demodulation in an FM demodulation circuit 1 and is inputted to a clamping circuit 2. The clamp circuit 2 makes clamping in accordance with the reference voltage from a 1st reference voltage generating circuit 6. The clamp output is converted to a digital signal in an AD converting circuit 3. The AD converting circuit 3 is inputted with the reference voltage from a 2nd reference voltage generating circuit 7 and corrects the input range and linearity of the AD conversion. The AD converted output is inputted to an error integrating circuit 4 and the respective reference voltages to the clamp circuit and the AD converting circuit are changed according to the AD conversion level corresponding to the reference signal.

Title: Frequency discriminator
Inventor: SAITOU TOSHIYUKI
IPC: H03D9/04
Filed: 1983-02-28
Abstract: PURPOSE:To equalize input signals to the phase detector in level and to improve the linearity and sensitivity of a microwave frequency discriminator by branching an input signal into two through a hybrid circuit, and applying one directly to the phase detector and the other through a BPF. CONSTITUTION:A high frequency signal is branched into two through a 3db hybrid circuit HYB-3; and a component 1 is branched into 90 deg. out-of-phase components 3 and 5 by an HYB-4 of the same phase detector PD. One component 2 is passed through the BPF and then branched into 90 deg. out-of-phase components 3 and 5. Voltages VD1 and VD2 applied to diodes D11 and D2 are equal in amplitude and in phase with each other at some frequency as shown in a voltage vector figure, so differential detection is performed to obtain an output voltage of zero V at R2. When an input frequency decreases, the component 2 advances in phase according to frequency characteristics of the BPF. Consequently, the voltages applied to the diodes are as shown in vector figures V'D1 and V'D2 and V'D1-V'D2 becomes positive after differential detection. On the other hand, it becomes negative when the input frequency increases.
