Method for safe formation of harmonic signal with use of broad-pulse modulation (BPM)

摘要

Method for safe formation of harmonic signal with use of broad-pulse modulation. Filtration of HF signal with variable on-off time ratio one performs by means of high frequency filter. With two channels one forms independent pulse high-frequency (HF) sequences with close frequencies and following application of logical operation “Exclusive OR”. Difference of frequencies of HF sequences is set as equal to frequency of resulting harmonic signal.
