Abstract

PURPOSE:To make a specific-interval receiving possible surely by controlling a counter for auto-tuning under a specific condition in an AM wave receiving. CONSTITUTION:The division ratio of programmable frequency divider 15 in frequency synthesizer part 11 is controlled variably by output N of counter 25 for auto- tunig, thereby performing the auto-tuning operaton. In this case, output N of counter 25 is branched and led into detector 26 for multiples of 9, and dependently upon whether output N is a multiple of 9 or not, IF detection pulses of detection part 22 are outputted through gate 27 to control the ON and OFF operation of pulse generator 28 which drives counter 25. As a result, the 9KHz-step broadcasting can be received surely.
