模拟信号的实时数字处理技术(因其将顺序的曲线形式象数字一样地去加以处理所以很吸引人)直到现在仅在特别高速的处理机中才能很快地完成必要的计算。这里介绍的NMOS组件给进行模拟系统设计提供了一种获取一台处理机的可能性。组件2920(Intel)是为支援电信调制和满足各种有可编程序单元的工序之迫切要求而产生的。它将A/D和D/A转换器和一个特别的微计算机组合在一起,制成一个器件。它有一组指令。它能使模拟量在组件中的子程序帮助下实现某些功能,诸如滤波、调制、解调、限幅、混频等等。这在平常就要求用许多无源组件,如运算放大器和其他一些分立元件才能完成。若在2920的外部稍加些部件就能将其接成调制解调器、(偏差)校正器、声源或接收器等。此外尚可用它进行程序控制和作为(伺服)电动驱动器使用。程序可编乃是这一实时信号处理的主要优点:它最终表现的功能将由同一基片上的EPROM(可改写的可编程序只读存贮器)中的内容来定。
Real-time digital processing of analog signals, which is attractive because it processes sequential curves like numbers, has until now been able to make the necessary calculations quickly only in exceptionally high-speed processors. The NMOS components presented here provide the possibility of obtaining a processor for simulation system design. The 2920 (Intel) component is designed to support telecommodulation and meet the urgent requirements of various programmable cell processes. It combines A / D and D / A converters with a special microcomputer to make a device. It has a set of instructions. It enables the simulation to perform certain functions, such as filtering, modulation, demodulation, clipping, mixing, etc., with the help of subroutines in the assembly. This usually requires the use of many passive components, such as operational amplifiers and other discrete components to complete. If the 2920 a little external components can be connected as a modem, (deviation) corrector, sound source or receiver. In addition it can still be used for program control and as a (servo) electric drive. Programmability is a major advantage of this real-time signal processing: the ultimate performance of the function will be determined by the contents of an EPROM (rewritable programmable read-only memory) on the same substrate.
