Title: Automatic frequency control circuit
Inventor: SAWADA HISASHI
IPC: H03J7/02
Filed: 1986-09-30
Abstract: PURPOSE:To perform a high-speed frequency pull-in action for each burst signal by using the same number of switches, low pass filters and sample holding circuits as the number of burst signals and selecting just a single channel out of the sample holding circuit. CONSTITUTION:An input signal 1 is mixed 2 with the output of a voltage control circuit 5 for output of a differential frequency signal. This frequency signal is supplied to a switch Sa or Sb after discrimination 3 of frequency. The switch Sa or Sb is kept ON for a period of presence of the burst input signal 1 by an AND 14a or 13b between a control signal 7 synchronous with a burst signal and burst designating signals 8a and 8b. The output obtained in such a case is transmitted through low pass filters 4a and 4b to undergo sample holding processes 6a and 6b. Then a frequency error signal is outputted to a scanner 12. The output of the scanner 12 controls the oscillation frequency of the circuit 5 and feeds it back to a mixer 2. Both sample holding circuits 6a and 6b are set under a holding mode when the signal 1 is absent and hold the final value of the frequency error signal. Thus a high-speed frequency pull-in action is carried out for each burst signal.
