在APPLEⅡe机上实现语声信号的输入输出接口

Interface Circuit for Input and Output of speech Signals in the APPLE Ⅱ e

用微处理机来控制语声信号处理时,要解决的首要问题是语声信号的输入和输出。本文介绍一种在 APPLEⅡe 机上实现语声信号的输入、输出的接口设计。

When digital processing of speech signals is controled by microcomputer,in- put and output of speech signals is the first question to solve.This paper deser- ibes the design of interface circuit for input and output of speech signals in the APPLE Ⅱe.
