Abstract
PURPOSE: To obtain a satisfactorily stable receiving function by multiplying or dividing the frequencies of the output of a quartz oscillator for a watch so that the output may be used as a local oscillating output.
CONSTITUTION: The output of an oscillatory circuit 1 is made to have its frequency multiplied into a desired frequency by a multiplying circuit 6 or divided by a frequency dividing circuit 2 so that it may be added through a buffer circuit 7 to a mixing circuit 9. On the other hand, the received electric waves are high frequency amplified and the are mixed with the output of the circuit 7 by the mixing circuit 9. After that, the mixed waves are intermediate frequency amplified at 10 so that signals can be produced from a detecting circuit 11.
