摘　　要：随着CMOS技术和集成电路技术的成熟,专用编解码集成电路越来越多地应用于公共系统中,使得系统设计简单化,同时可靠性提高。PT2262/2272是一对带地址/数据编码的专用编解码集成电路。利用PT2262/2272的“地址识别”特点,设计了一种无线报警电路。在发出报警信号的同时,给出报警点位置代号,给出了详实的原理电路。Along with the development of the CMOS and integrated circuit technology, the special coder and decoder IC is widely used in the public system, which simplify the system design and meanwhile enhance the system reliability. PT2262/2272 is a pair of special coder and decoder IC with address/data pins. A kind of wireless alarm circuit which displays the position code is designed, while alarming by using of the ＂address identification＂ feature. The principle circuit is presented.
