Title:
IMPULSE WAVEFORM GENERATING APPARATUS AND HIGH FREQUENCY PULSE WAVEFORM GENERATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2006/106718
Kind Code:
A1
Abstract:
An impulse waveform generating apparatus comprises a multistage delay pulse signal generating part for generating a plurality of delay pulse signals from a timing signal; a signal source signal generating part for generating, from the delay pulse signals, a signal source signal indicative of the frequency component of an impulse waveform signal; an envelope formation signal generating part for generating, from the delay pulse signals, an envelope formation signal indicative of the amplitude component of the impulse waveform signal; and a mixer part for multiplying the signal source signal by the envelope formation signal to generate a predetermined 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.
