Abstract
There can be solved a problem in which a lock range is narrowed by using an oscillator such as a ceramic having a high Q and a horizontal deflection frequency generating system compatible with all horizontal deflection frequencies of a variety of television systems cannot be formed without difficulty. This system includes a frequency-fixed oscillator oscillating at a frequency f sufficiently higher than a deflection frequency fh in a multi-scan display, a first counter for counting a clock outputted from said oscillator in a descending order, a duration in which an integer n which results from rounding a decimal point of a value obtained by a division of f fh is divided by an integer m smaller than n and said first counter counts a value k thus obtained k times is set to one cycle and a duration in which a second counter for counting a value m times repeats the counting m cycles is set to one period and thereby generating a deflection frequency fh.
