摘要
本文探讨了应用单板机作为多功能的激励信号源,自编计算机程序,在TP-801B单板机上实现快速正弦扫频信号和伪随机信号输出时,应解决的几个问题。对应用单板机产生快速正弦扫频信号的方法,目前尚末见到有关的文献和报道。该方法比过去使用专用信号发生器来产生快速正弦扫频信号优越得多。经在实际结构试验中应用,证明单板机作为多功能的激励信号源是较为理想的激励信号源。
This paper discusses several problems caused by the production of ths rapldfreguency sweep signal and the pseudo--random signal in SBC TB--801B by ourown designed computer programs, Using SBC as a multifunctional excitation sig--nal source. It hasn't been reported that the rapid freguency sweep signal is pro--duced by SBC. This method is superior to that of the production ot the rapidfreguency sweep signal by the special signal generator. Practical structure testsshow that SBC can be used as a better multifunctional excitation signal source.
