Patent JP-S5579534-A (JP)
Title: Afc circuit system
Inventor: FUJIKAWA SHIYUNJI
IPC: H03L7/10
Filed: 1978-12-11
Abstract: PURPOSE:To display rapidly an abnormal state according to a decision result when a step-out state occurs, by deciding a shift in frequency and its direction by invariably comparing a transmission-synchronous reference pilot signal frequency with the output signal frequency of an oscillator to be controlled. CONSTITUTION:Voltage control oscillation circuit VCO5 of an automatic frequency control circuit provided to a PLL circuit generates a frequency signal approximate (n) times as high as an input reference pilot signal, and divider circuit 6 divides its frequency by (n), thereby making a phase comparison with the input pilot signal by a phase comparator circuit 2. The output of circuit 2 is fed back to VCO5 by way of switch circuit 4. The output of this circuit 2 is applied to level detection circuit 7 to exercise a supervision over whether a shift in frequency is within an allowable extent at any time and also to decide upon its direction; when it exceeds a fixed value, the loop is disconnected by circuit 4 and an abnormal state is outputted to terminal 14 and then displayed. Further, a sudden change in pilot signal is detected by frequency comparator circuit 12 and acquisition-of-synchronism decision circuit 13 disconnects the loop and outputs a display signal.
