| Abstract: | The design concept of a novel digitizing method to traditional low frequency amplifier is proposed.The amplifier is based on OCL power-amplifying unit,MSP430F5438 micro-controller,LCD and singal-processing unit.Parameters of output power,conversion efficiency and others are detected timely with 12-bit ADC modules in MCU.The structure of this circuit is simple.Results of experiments show that the power amplifier has good performance in some aspcets,such as bandwidth,distortion factor,efficiency and so on. |
