1.前言毫无疑问,今日广播技术的发展主要依赖于晶休管技术的进步(从电子管到晶体管再发展到集成电路)。现从晶体管、集成电路以至微电子技术的急速发展来看一下电子技术发展 1. Foreword There is no doubt that the development of broadcasting technology today depends mainly on the progress of crystal-break technology (from tubes to transistors to integrated circuits). Now from the transistor, integrated circuits and even the rapid development of microelectronics to look at the development of electronic technology
