Abstract
A frequency divider for converting an n-bit periodic counting stream (each period containing a single zero or one bit, respectively, followed by n-1 one or zero bits) into a 2n-bit counting stream includes a two-input NOR gate or NAND gate, respectively, connected for delivering its output to an n-bit delay device, the NOR or NAND gate further connected for receiving the output of the delay device as feedback at one of its two-input terminals and for receiving the n-bit counting stream at the other of its two-input terminals. The output of the delay device is then a 2n-bit counting stream.
