一、数字式与模拟式声频信号处理 数字式声频信号处理与模拟式方法相比具有下述优点:(1)信号处理与存贮的动态范围可达90分贝以上;(2)非线性畸变小于0.05％;(3)相邻通道间立体声的串话衰减可达85分贝以上;(4)互调失真和描纹畸变几乎测不出来;(5)例于采用有效的抗干扰和数据保护方法;(6)有可能对声信号进行数字式加工(如加入混响效果或按照艺术观点进行加工等)、精确地可再生地存贮和无误差地复制等.
A digital and analog audio signal processing Digital audio signal processing has the following advantages compared with the analog method: (1) signal processing and storage of dynamic range up to 90 dB or more; (2) the nonlinear distortion is less than 0.05%; (3) crosstalk attenuation between adjacent channels up to 85 dB or more; (4) intermodulation distortion and portrayal distortion almost undetectable; (5) in the case of effective anti-jamming and data protection methods ; (6) it is possible to digitally process the acoustic signal (such as adding a reverb effect or processing it from an artistic point of view), precisely reproducibly storing and copying without error.
