A modulation system is provided with a data analyzer detecting input of a modulated data and a modulation clock signal and latching and detecting an edge of the modulated data, in response to the modulated data and the modulation clock signal, a signal controller, responsive to an output of the data analyzer, carrying out an operation process with respect to the frequency deviation data and carrying out one of a frequency deviation amplitude control operation and a frequency deviation time control operation, a digital-to-analog converter converting an output of the signal controller into an analog signal, and a transmitting unit transmitting an output of the digital-to-analog converter.
