Abstract

The invention discloses a signal modulation method, a signal modulator and a signal modulation system. The signal modulation method comprises the steps of accessing a data signal; accessing a data signal and a carrier signal; extracting a carrier signal in a first level period of the data signal to obtain a first carrier signal; detecting the edge of the data signal to generate a first pulse signal associated with the edge, wherein the amplitude V1 of the first pulse signal is greater than the amplitude V2 of the first carrier signal; superposing a first carrier signal on the first pulse signal to obtain a transmission carrier signal; performing capacitive coupling output on the transmission carrier signal; and receiving the transmission carrier signal subjected to capacitive coupling andperforming data recovery to obtain a data signal. According to the embodiment of the invention, the edge modulation mode is realized through the first pulse signal, the on-off keying modulation mode is realized through the first carrier signal, the signal modulation method combines the two modulation modes to improve the transmission quality of the modulation signal and the control accuracy of thedata information, and the signal modulation performance is better.

Description

technical field [0001] The invention belongs to the technical field of signal modulation, and in particular relates to a signal modulation method, a signal modulator and a signal modulation system. Background technique [0002] With the rapid development of electronic technology, technicians often need to combine multiple circuit systems to achieve complete and complex circuit functions. However, due to the different electronic components and signal transmission environments in each circuit system, for example, each circuit system It has its own reference ground potential, and the electrical energy is connected to the circuit system to be in a normal working environment. The reference ground potential between different circuit systems will have a voltage difference of up to several thousand volts; therefore, considering the difference in signal transmission between circuit systems, It is necessary to transmit control signals between multiple circuit systems through isolation...
