<p>A digital frequency divider, for producing an output signal related in frequency to an input signal by the ratio less than unity Z/N, incorporates an exclusive-OR gate and three frequency dividers having divisors m, n and k. The fraction Z/N is realized where n and k are integers, and the divisor m is chosen by: <IMAGE> When m is not an integral number, its corresponding divider is embodied by a cascaded divider circuit made up of two or more cascaded units each including an exclusive-OR gate and at least two frequency dividers connected to yield a fractional divisor.</p> |
