22、4 年才出现第一台全晶体管的信号发生器。自 60 年代以来信号发生器有了迅速的发展，出现了函数发生器，这个时期的信号发生器多采用模拟电子技术，由分立元件或模拟集成电路构成，能产生正弦波、方波、锯齿波和三角波等几种简单波形。函数信号发生器是一种常用信号源，它广泛地应用在电子技术实验、自动控制系统和其他科研领域。它能够产生正弦波、方波、三角波、锯齿波等多种波形，因其时间波形可用某种时间函数来描述而得名。函数信号发生器在电路实验和设备检测中具有十分广泛的应用。例如在通信、广播、电视系统中，都需要射频高频）发射，这里的射频波就是载波，把音频低频）、视频信号或脉冲信号运载出去，就需要能够产生高频的振荡器

23、。在工业、农业、生物医学等领域内，如高频感应加热、熔炼、超声诊断、核磁共振成像等，都需要功率或大或小、频率或高或低的振荡器。信号发生器的应用非常广泛，种类繁多。首先，信号发生器可以分通用和专用两大类，专用信号发生器主要为了某种特殊的测量目的而研制的，如电视信号发生器、脉冲编码信号发生器等。这种发生器的特性是受测量对象的要求所制约的。其次，信号发生器按输出波形又可分为正弦波信号发生器、脉冲波信号发生器、函数发生器和任意波发生器等。再次，按其产生频率的方法又可分为谐振法和合成法两种。一般传文档编码:CN7S4U8X7D10 HU3T6N10R8H1 ZL3I10K5O2O3文档编码:CN7S4U8
