ABSTRACT:
A multimode communications system includes a first communications module, a transmission module, a switch and a second communications module. The first communication module has a frequency modulator for modulating a dividing ratio to adjust an oscillating signal and selectively enabling the oscillating signal to have its frequency change with a variety of contents of a first communications signal by modulating the dividing ratio according to the contents of the first communications signal on a modulating mode or enabling the oscillating signal to have its frequency constant by keeping the dividing ratio unchanged. The switch is to selectively transmit the oscillating signal either to the transmission module when the frequency modulator is operating on the modulating mode or to a receiving end when the frequency modulator is operating on the constant frequency mode.
