基于Multisim波形产生电路设计 [摘要]当代电子技术迅速发展，为人们的物质文化生活提供了优越的条件。 Waveform Circuit Design based on Multisim [Abstract] The electronic technique of the contemporary era is developing rapadily, it provides a superior condition for the material and cultural life of urban and rural,Digital video,home theater, air conditioner,computer and so on, are all typical examples of application on electronic technique .The boundaries between hardware and software is increasingly blurred. Artificial circuit and digital circuit are both hardware, when we exploit software to do computer aided design ,We can proceed waveform simulation. In view of the difficulties and requirements of teaching and learning on current electronic technique, the ational instrument Co., LTD provides a powerful solution,it is just the NI electronic education platform.The NI electronic platform is making effective links between theory, the simulation analysis and hardware experiments.It is able to provide users with practical circuit simulation data.It can also provide a unified platform for comparing and analysing of the simulation data and the measured data. This paper mainly studies the waveform circuit and the related circuitry principle,it studies the specific role of each part of the analogue waveform circuit.It mainly includes three-point capacitance oscillatory circuit, sine wave rc oscillator circuit without a steady amplitude,sine wave rc oscillator circuit with a steady amplitude, a duty cycle nonadjustable circuit of wide band square-wave generator ,a duty cycle adjustable circuit of wide band square-wave generator,saw-tooth circuit, it uses resistor, capacitor,diode ,zener diode ,triode, integrated operational amplifier, and so on.
