引言电刺激的方法在生理学、医学研究及临床诊断上广泛应用。目前,国内虽已生产了多种类型的晶体管分立元件刺激器和数字式刺激器,但晶体管刺激器大都功能不全,控制不够精确,稳定性较差数字式刺激器虽然克服了上述缺点,但输出幅度较低,电路复杂,控制不变。随着微机技术在生物医学工程领域的广泛应用,国外,Meadows等研制用IBM PC/AT计算 Introduction The method of electrical stimulation is widely used in physiology, medical research and clinical diagnosis. At present, although many types of transistor discrete stimulators and digital stimulators have been produced domestically, most of the transistor stimulators are not fully functional, the control is not accurate enough and the stability is poor. Although the digital stimulator overcomes the above shortcomings, the output Low amplitude, complicated circuit, the same control. With the widespread application of microcomputer technology in the field of biomedical engineering, Meadows and other foreign countries with IBM PC / AT
