Abstract
PURPOSE: To make it possible to incorporate a broadcast receiver in a wristwatch by obtaining the local oscillation frequency of the broadcast receiver by synthesizing signals of the time standard oscillator of the electronic watch.
CONSTITUTION: From signals, which are divided by frequency divider 20, of time standard oscillator 19 of an electronic watch which is set to a frequency of integral multiples of a received broadcast frequency interval, a local oscillation frequency is synthesized by a channel selection mechanism consisting of phase comparator 24, filter 25, voltage control oscillator 26 and programmable frequency divider 27 and is used as the local oscillator signal of frequency converter 30 of a broadcast receiver.
