介绍了基于单片机航空交流电参数测试仪的系统设计。以Silicon Labs公司的C8051F005单片机为核心设计出数据采集板，通过RS-232串口与上位机通讯。运用Lab Windows/CVI编写的上位机软件实现信号的检测以及波形和数据的显示，给出了测试仪硬件电路的组成和软件流程图。本系统具有硬件结构简单、容易实现和成本低等特点，在实际 ...

随着单片机功能集成化的发展，其应用领域也逐渐地由传统的控制，扩展为控制处理、数据处理以及数字信号处理（DSP，Digital Signal Processing）等领域。凌阳的16位单片机就是为适应这种发展而设计的。它的CPU内核采用凌阳最新推出的µ’nSP™（Microcontroller and Signal Processor）16位微处理器芯片（以下简称 ...

This application note describes how to decode standard DTMF tones using the minimum number of external discrete components and a PIC. The two examples use a PIC which has an 8 bit timer and either a comparator or an ADC, although it can be modified for use on a PIC which has only digital I/O. The Ap ...

　　The power of programmability gives industrial automation designers a highly efficient， cost-effective alternative to traditional motor control units （MCUs）。 The parallel-processing power， fast computational speeds， and connectivity versatility of Xilinx® FPGAs can accelerate the impl ...

Mobile phones are constantly decreasing in size, thereby complicating the acoustical functionality. Signal processing methods can be used to partially mitigate this problem. In this paper we suggest a method which uses multiple spectral subtraction functions and two microphones, introducing only a s ...
