FM MODULATOR COMPENSATING MODULATION CHARACTER CHANNEL

摘要

The FM modulator comprises a controller for providing data to assign the channel by sensing a transmitting/receiving channel and for generating a switch control signal corresponding to each channel. A frequency compensator compensates for frequency characteristics according to each channel by regulating a gain of an input channel using the switch control signal from the controller. A capacitance converter converts a given voltage value from the frequency compensator into a capacitance value. A resonator generates a given resonance frequency with the capacitance value of the capacitance converter. A voltage controlled oscillator generates an oscillation frequency to modulate the corresponding frequency based on the resonance frequency.
