Abstract

PURPOSE:To provide an attenuator and a DC amplifier at the input teminal of a voltage control oscillator in order to ensure almost a constant gain ratio of the voltage control oscillator against the division ratio of a programable divider. Thus, a constant reply can be secured for the phase lock loop.
