基于单片机控制的数控功放的设计

摘要

The paper designs a numerical control power amplifier based on a single-chip AT89s51 as the core controller and SC7313 for electronic volume disposal. The front of the sound field such as volume, pitch and loudness is dealt with the pure digital control. The communication is I2C bus between communication storage module、numerical control module and control module.%　　针对市场上功放参数均是模拟控制为主的状况，本文设计一款以单片机 AT89s51为核心控制器、SC7313为电子音量处理的数控功放，将功放的前端声场如音量、音调、响度等采用纯数字化控制和处理。存储模块、数控模块以及控制模块间主要采用 I2C 总线协议进行通信
