Filed: 1978-08-30
Abstract: PURPOSE:To lessen the deterioration of the practical sensistivity even with the specified frequency by securing a connection between the prescaler output end which divides the frequency of the voltage control oscillator and the input of the PLL circuit via the LPF. CONSTITUTION:The LPF consisting of resistance 12 and capacitor 13 is inserted between prescaler 6 which divides the frequency of VCO (voltage Control Oscillator) 5 and the input of PLL part 7.
