Impulse waveform generating apparatus and radio-frequency pulse waveform generating apparatus |
摘要 |
An impulse waveform generating apparatus includes a multistage delay pulse signal generating part for generating a plurality of delay pulse signals by a timing signal; a signal source signal generating part for generating a signal source signal indicating the frequency component of an impulse waveform signal by the delay pulse signals; an envelope formation signal generating part for generating an envelope formation signal indicating the amplitude component of the impulse waveform signal by the delay pulse signals; and a mixer part for multiplying the signal source signal by the envelope formation signal to generate a prescribed impulse waveform signal. The impulse waveform generating apparatus generates the impulse waveform signal from the timing signal. Therefore, the circuit arrangement requires no digital-to-analog converter, the operational frequency of each element can be reduced, and the power consumption can be reduced. |
