A low emission signal manipulating circuit for reducing emission of a given signal. This is accomplished by manupulating the signal and recovering the original signal. The inventive device includes a transmitter which modifies a given signal, a divider that resides in transmitter which divides the incoming signal, a pulse shaping circuit which generates two pulses one at the leading edge and one at the trailing edge of the incoming signal, a receiver which recovers the original signal from the modified signal, a register which generates a signal based on incoming pulses, a phase locked loop circuit that generates a signal at the output. Transmitter has a divider circuit that divides the incoming signal. It also has pulse circuits where two pulses are generated. Divider has five flip flops that divides the incoming signal's frequency by a predetermined amount. Pulse shaping circuit has two integrators and logic gates. Receiver has a register circuit and phase locked loop. Register has a flip flop. Phase Locked Loop has a phase comparator, charge pump, voltage controlled oscillator and a divider.
