基于CPLD单双极性码转换电路的设计与实现

Designing and Realizing Single-Double Pole Code Circuit Based on CPLD

以某型飞机无线电高度表检测仪研制为背景,通过采用CPLD器件和VHDL硬件语言,设计实现了一种能替代该无线电高度表检测仪检验组合功能的单双极性码转换电路,并给出了VHDL程序和相应的时序仿真波形。

Taking the development and research of a certain type of aircraft radio altimeter as a background and using CPLD and VHDL hardware language, this paper designs and realizes a kind of Single - Double pole code switching circuit which ean replace the original detecting function of the radio altimeter detector, finally gives out VHDL programmers and the corresponding time sequencing simulation waveforms.
