摘要： The invention relates to a high-mode self-oscillating pulse modulator. According to the invention, a complete rethinking of preconditions for oscillation and modulation in an oscillating modulator as all conventional thinking of how to apply oscillation in a modulator has been set aside. Thus, according to the invention, high-mode oscillation refers to an oscillation at a higher mode than the first mode, which is conventionally regarded as the one and only applicable mode in an oscillating modulator.
