Abstract: A transmission device for multi-frequency equal-amplitude non-harmonic electrical prospecting signal includes a single-chip microcontroller, a field programmable gate array (FPGA), a digital to analog conversion (DAC) module, an isolation amplifier circuit, a differential amplifier module, a digital power amplifier circuit, and a sensor module connected successively. A plurality of output ends of the digital power amplifier circuit is in cascade connection with a grounding electrode A and a grounding electrode B to form a loop with ground. An input end of the sensor module is connected with the digital power amplifier circuit. An output end of the sensor module is connected with the single-chip microcontroller.
