Abstract

The invention relates to a method and a device for synthesizing and transmitting a waveform signal. The device comprises a processor and a DA converter, wherein the processor is provided with an internal storage and a high-speed synchronous serial interface; a sinusoidal waveform signal processed by the processor is converted into waveform data and used for storing the waveform data in the internal storage of the processor; an address pointer of an access module of a direct storage points to a storage address for the waveform data; the access module of the direct storage directly controls the stored waveform data and transmits the data to the data analog converter through the synchronous serial interface; and the data analog converter synthesizes and coverts the received waveform data into an analog signal, and then outputs the signal. The invention further comprises a method for using the device. The invention has the characteristics of simple structure, saved cost and easy control.

Description

technical field [0001] The invention relates to a method and device for synthesizing and transmitting waveform signals, in particular to a method and device for converting digital signals into analog waveform signals for synthesizing and outputting. Background technique [0002] In the output process of the waveform signal of the AC power source, the waveform signal needs to be synthesized and then output as an analog signal. Especially in the power system, various kinds of program-controlled AC power sources are widely used, and this AC power source can output sine wave signals with different phases and superimposed different harmonics. In the prior art, as shown in Fig. 1, according to the final output waveform signal, generally these waveform signals that need to be synthesized are first converted into digital signals, and then these digital signals are stored in the external memory, and designed in the programmable logic device A complex sequential circuit that controls...
