Accuracy of measuring radar carrier frequency with traditional analogue receiver is low, and not satisfying. However, with Large Scale Integrated circuit technique development, many excellent digital methods of measuring frequency can be used in digital receiver. 传统的模拟接收机测频精度较低,已经无法满足实际的测频需要,而随着大规模集成电路的发展,许多性能优异的数字测频算法能在数字接收机中得以应用。
At present, the motion controller is divided into all sorts of analogue circuit, micro control unit, programmable controller, general computer, application specific integrated circuit ( ASIC), programmable logic device and digital signal processing ( DSP). 目前运动控制器可分为基于模拟电路、微控制单元、可编程控制器、通用计算机、ASIC、可编程逻辑器件和DSP等类。
