Abstract
A signal transmitter includes a modulation circuit, a signal separation circuit, and a signal combining circuit. The modulation circuit modulates a first signal to a modulated signal. The signal separation circuit separates the modulated signal into N separated signals. The N separated signals have different phases. The signal combining circuit combines the N separated signals to eliminate at least one order of harmonic signals of the N separated signals so as to generate an output signal.
