本文介绍一种适合业余爱好者装制的集成电路信号发生器,该发生器能产生黑底白条的格子图案。从音频振荡电路取出音频信号,可供检修收录机、电视机低放部分用。并且制作简单,调试方便。用一根电视拉杆天线,可发射200m左右,不用天线可发射10m左右。
This article presents an integrated circuit signal generator for hobbyists that creates a black-and-white striped pattern. Remove the audio signal from the audio oscillator circuit for overhaul tape recorders, low-cost part of the TV. And making simple, easy debugging. With a TV antenna rod can be fired about 200m, without the antenna can launch about 10m.
