ABSTRACT:
A frequency divider, constituted by N divide-by-two binaries, comprises logic circuits that enable the generation of a signal of the end of the frequency division by means of the change in state of the most significant bit generated by the Nth order divide-by-two binary. A binary code C representing a decimal integer value V is applied to the divider circuit. The frequency divider comprises circuits that enable the performance of a variable order division (V+1, V, . . . V-p, where p is a whole number greater than or equal to 1 and smaller than N-1) for one and the same binary code C.
