为了满足现代高速通信中频率快速转换的需求,基于坐标旋转数字计算(CORDIC,Coordinate Rotation Digital Computer)算法完成正交直接数字频率合成(ODDFS,Orthogonal Direct Digital Frequency Synthesizer)电路设计方案。采用MATLAB和Xilinx System Generator开发工具搭建电路的系统模型,通过现场可编程门阵列(FPGA ...
Abstract: Many digital devices incorporate analog circuits. For instance, microprocessors, applicationspecificintegrated circuits (ASICs), and field-programmable gate arrays (FPGAs) may have internalvoltage references, analog-to-digital converters (ADCs) or digital-to-analog converters (DACs). How ...
Abstract: It is incredible how many programmable logic controls (PLCs) around us make our modern life possible and pleasant.Machines in our homes heat and cool our air and water, as well as preserve and cook our food. This tutorial explains the importanceof PLCs, and describes how to choose compon ...
Abstract: Using a DAC and a microprocessor supervisor, the system safety can be improved in industrial controllers, programmablelogiccontrollers (PLC), and data-acquisition systems. The analog output is set to zero-scale (or pin-programmable midscale) when amicroprocessor failure, optocoupler fail ...
This unique guide to designing digital VLSI circuits takes a top-down approach, reflecting the natureof the design process in industry. Starting with architecture design, the book explains the why andhow of digital design, using the physics that designers need to know, and no more.Coverin ...
