In the figure is the digit controlled frequency splitter and Figure (a) is the principle circuit. The circuit can set any splitting constant and output a square wave. To a random even number N, the N can be written as N=2M, and to a random odd number, which can be represented as N=2M+1. If N is represented in the binary way, the minimum binary bit may be removed and it gets M, so the frequency splitting constant can be controlled by the binary number. Therefore, to a certain N, we can design a M frequency splitter. For example, if N=181, then the M added on the splitter will be 90.
