发明名称 Frequency divider of pulses using ring-counters
摘要 A frequency divider for dividing input pulses by a predetermined number is formed of an input means for receiving input pulses, a plural number of counters, each having a series connection of stages through which a count signal is respectively shifted in response to the input pulses. The numbers of series stages being selected so that they do not have any common divisor and have a minimum common multiple larger than the predetermined number pulse one. The frequency divider also includes a detecting means for detecting common occurrence of said count signals at selected stages of respective counters, and an output means for producing an output pulse in response to the detection by the detecting means.
