摘要
把方波调频及脉冲间隔与宽度调制同视为周期性调制的方波，采用一种静态近似法得到脉冲间隔与宽度调制信号的逼近谱表示及方波调频信号的谱表示，并由硬件模型提供的实验结果予以确认。
Both squarc wave frcquency modulation and pulse interval and width modulation are reviewedas a period-inodulation square wave and an approaching cxpression of spectrum for pulse in-terval and width modulation is found using a statie approach.Moreover an expression of spec-trum for square wave frequency modulation is derived also.These expressions and proposedmethod havc been confirmed by experimental results which are provided using hardware models.
