Abstract
PURPOSE:To improve response speed at the time of the input of a sweeping signal without damaging the characteristic of a circuit by providing a differentia tion circuit part and an OFF detecting part for detecting the rapid change of an AGC voltage and detecting an OFF state thereof and deciding an output according to the three outputs of a comparing part, a pulse detecting part and the OFF detecting part. CONSTITUTION:The differentiation circuit part 6 and the OFF detecting part 7 for detecting the change of the AGC voltage are added to input the output of the OFF detecting part 7 to a logic part 5 together with the respective outputs of the comparing part 3 and the pulse detecting part 4. The differentia tion circuit part 6 and the OFF detecting part 7 detect the rapid change of the AGC voltage and output it to the logic part 5. Since the time constant of the differentiation circuit part 6 is set to the time constant of an AGC loop, an abnormal (squelch) output can be rapidly transmitted without being influenced by the time constant tau of the pulse detecting part 4 even at the time of a signal OFF to the time of inputting the sweeping signal.
