The signal consisting mainly of white noises with >=100kHz in the said demodulation signal passes through the HPF and the result is fed to a frequency converting circuit 101. Further, a signal of <=100kHz being an FM detection output from the terminal B is inputted to an FM stereo demodulation circuit 200 of the PLL system to obtain left/right stereo demodulation signals. An output of a VCO203 of the circuit 200 is subject to frequency division 204, a signal outputted from a terminal H is fed to the circuit 101, a signal converted into an AM intermedi ate frequency signal from the circuit 101 is amplified (102) and detected (103) to obtain a detection signal of a noise level from a terminal E. Since the white noise level corresponds to the electric field strength of a reception signal, the electric field is detected by the noise level.

Title: Phase controller
Inventor: YAMAOKA KATSUMI
IPC: G11B19/28
Filed: 1983-11-04
Abstract: PURPOSE:To shorten the time required to control a controlled variable to a command by controlling a control system with a steady-state realizing signal instead of a phase control signal when the control system deviates from a steady state. CONSTITUTION:A phase controller controls a motor M so that the phase of the output signal of the frequency generator FG of the motor M leads the phase of a reference signal. A reference signal generating circuit 1 incorporates an oscillator and its frequency divider and outputs the reference signal when a reset signal is ceased. A phase comparator 2 detects the phase difference between the reference signal and the output signal o a pulse generator PG to input it to one terminal of a switching circuit 4 through a loop filter 3, and a steady-state realizing voltage EP is applied to the other input. This circuit 4 is placed normally at the side EP and switched with a switching signal rom a control part 8. Consequently, if the control system deviates from the steady state in power-on operation, the steady-state realizing voltage EP is applied to the speed control system and the phase control signal is supplied almost in the steady state.
