Abstract
A programmable frequency divider includes a programmable counter which comprises flip-flops 1 to 11 of a number less by one than the number of bits in a program value. The divider has first and second control circuits 101, 102 which respectively control every half period of a preset divided output pulse alternately, the second control circuit acting to delay the moment of the control in response to the least significant bit having a selected logic level, thereby enabling one to reduce the clock pulse frequency to a half in comparison with a conventional one. One can also obtain an optional sub-output signal of twice or one-half the frequency of a preset frequency output signal. Refer to FIG. 2.
