摘要
信号发生器电路在电气实验与工程领域应用广泛。为满足实验教学需要,基于LM324芯片自主设计了一款集成三角波发生器电路、加法器电路、滤波器电路及比较器电路的信号发生电路。通过精心设计与计算各元件参数,利用Multisim软件绘制并仿真电路图,验证了设计方案的可行性。仿真过程中,重点观察了波形的形状,评估了信号是否失真,以确保满足实验要求。该发生器设计简洁,成本低廉,通过调整元件参数灵活提升信号发生器性能,以期为电子实验教学提供重要参考。
Signal generator circuits are widely used in the electrical experiments and engineering fields.To meet the needs of experimental teaching,a signal generator circuit,which consists of a triangular wave generator circuit,adder circuit,filter circuit and comparator circuit is designed independently based on the LM324 chip.Under the given experimental requirements,through the design of the circuit and the calculation and setting of the parameters of each component,the use of Multisim to draw circuit diagrams for simulation,to verify the feasibility of the circuit design,to observe the shape of the waveform,to determine whether there is distortion in order to meet the experimental requirements.The generator circuit is easy to do,less consumables,according to adjust the parameters of the components to improve the function of the signal generator circuit,can also be used for electronic experiments for reference.
