Abstract:

To achieve better MP3 audio output quality, this thesis makes research of D/A chips that most MP3 players to ultimately make the decision of using one-bit DAC as the way of DAC and audio output. And this overall design scheme is given out as well. Decoding MP3 files through upper computer software of PC and transmitting data to one-bit DAC module through serial ports. DAC is realized in FPGA chip through Verilog Language. And high shelf is used in the output section of one-bit DAC module. Finally, analyzes the output audio frequency of one-bit DAC module, surveys general performance of the overall play system and DAC module.[1][2]
