摘要：the communication system (10) for producing an output signal at a selectedfrequency with the primary bit serial digital data modulated manner through the use of amodulatphase shift differential ion dpsk) hybrid. the improved dpsk modulationfrequency modulation of a signal to the coding phase.a control device (12) controlsfrequency generators (14, 16), which produces a frequency difference between thefrequency of the output signal of the primary and secondary.the control device (12) and afrequency generator (14 and 16) to produce an output signal which is a modulated dcbalance bit by bit and has a harmonic energy meaningiblement reduced.
