Title: Phase locked loop oscillator
Inventor: TAKAHASHI YASUSHI
IPC: H03L7/107
Filed: 1987-12-28
Abstract: PURPOSE:To decrease the convergence time at the end of pull in by varying a loop gain of a phase locked loop in response to an input/output frequency difference. CONSTITUTION:A phase difference data PD is inputted for each control period, a difference from the preceding data is checked and when there is no difference, the pull in is finished. If the phase difference data PD is changed, its absolute value is checked and if the value is smaller, the loop gain G is halved. When the loop gain G reaches a preset minimum value Gmin, the pull in is finished. The control value CNT is calculated from the said loop gain G and the phase difference data PD and given to a frequency synthesizer 4. Thus, the converting time till the input output frequency is synchronized after the pull in is finished, is decreased.

Abstract: PURPOSE:To execute a decision that has few errors with simple constitution by generating a frequency component of a difference between 1st and 2nd carrier signals and deciding the existence of the 2nd carrier signal when an amplitude of this difference component is more than a prescribed value. CONSTITUTION:The 1st and 2nd carrier signals are both taken out by a band pass filter 25, and this filter output is supplied to an envelope detecting circuit 26 where even number-th degree distortion, mainly a difference frequency component is generated, and this component is taken out by a band pass filter 27.

Consequently, the need for application of a narrow band to the band pass filters is eliminated, so that a circuit configuration can drastically be simplified. By this method, an erroneous decision can excellently be prevented with simple constitution.
