Abstract

The invention provides a signal frequency multiplication circuit, method and applicable equipment. Wherein, the signal frequency multiplication circuit of the present invention includes a signal input terminal, and the circuit also includes: a frequency determination control unit connected to the signal input terminal, including: a determination input terminal, a first strobe terminal, a second strobe terminal, a second strobe terminal, Three gate terminals, a fourth gate terminal, a first output terminal, and a second output terminal, wherein the determination input terminal and the first gate terminal are connected to the signal input terminal, and the first gate terminal and the second gate terminal are The received signal is output from the first output terminal, and the signals received by the third strobe terminal and the fourth strobe terminal are output from the second output terminal; the digital frequency multiplier connected to the signal input terminal and the second strobe terminal unit; an analog phase-locked loop connected to the first output terminal and the second output terminal, wherein, the output terminal of the analog phase-locked loop is also connected to the fourth gate; and the output terminal of the analog phase-locked loop and the third gate end-connected frequency divider. The invention can simultaneously solve the problems of too long time-consuming processing of low-frequency signals by analog frequency multiplication and easy generation of harmonic leakage when digital frequency multiplication performs frequency multiplication processing of high-frequency signals.

Description

technical field [0001] The invention relates to a signal frequency multiplication technology, in particular to a signal frequency multiplication circuit, method and applicable equipment. Background technique [0002] Signal frequency multiplication technology is mainly used in harmonic measurement, and its technical field involves power quality, frequency converter, engine, switching power supply, and new energy fields. For example, after the transmitter adopts a frequency multiplier, the main oscillator can oscillate at a lower frequency to improve frequency stability. FM equipment uses a frequency multiplier to increase the frequency offset. In the phase keying communication machine, the frequency multiplier is an important component of the carrier recovery circuit. Stable, low harmonic leakage frequency multipliers can improve the operating quality of the equipment in which they are installed. [0003] At present, there are mainly two types of frequency multipliers: an...
