Design and Realization of Low Frequency Transmitter Based on Waveform Synthesis
When applying the transient electromagnetic method,the regular signal tends to be distorted in the process of passing through perceptual load.In order to minimize the distortion effect,flexible and controllable signal should be generated.This paper puts forward the thinking of the low frequency transmitters based on the waveform synthesis,reaching the conclusion of combining design scheme with controller technology and DDS technology.Finally,the test can output three types of wave,whose frequency and amplitude are flexible and controllable,with an error rate less than 3%.The scheme,which lays the foundations for flexible and adjustable arbitrary waveform and simulates the target information dynamically,is highly practical.
