摘要
本文根据非线性语音数字码的特点，分析了量化值与数字码之间的数值关系。并利用运放的求和特点，导出了一种由运放，电阻和开关组成的非线性解码电路。与电流加权的非线性解码电路相比，用电压源代替了复杂的电流源，在电路上得到了较大的简化。
This paper analysed the number relation between the quantizing value and digitalcode according to the treit of the noulinear voice digital code,By employing thc trait ofsumming of opcmtional amplmer,the no nlinear decoding circuit which consists of theopemtional amplirlers,resistors and switchca is deduced,Compared with the nonlineardecodinly circuit of current adding by using the voltage source instead of the comolex cur-rent source、it is mole simole in circuit realizing than before.
