摘要
信号发生器能够发出使用者所需现场模拟的信号,受到了广大电子、电气等技术人员的欢迎.介绍一种结构简单、携带和使用方便的手持式信号发生器,它不仅能够向用户提供所需的方波信号,且频率调节精度高,还可以检测外部信号的频率及柴油机的转速,着重讨论了该信号发生器的结构原理、硬件电路设计,并给出了程序设计流程.
A signal generator can provide users with field analogue signals, so it comes into favour by electronic or electrical technicians. In this paper, a new set of portable SG was designed with simple circuits, which can output the square wave of adjustable frequency with high adjustable precision for the users. The new generator can be easily used to measure the outside signal frequency and the rotational speed of diesel engine （RSDE）. The construction, principle and circuit of this SG are emphatically discussed, and a flow chart of the program is provided.
