摘要
采用单片机AT89C51作为系统的控制核心,由DA转换器DAC0832及函数发生器ICL8038实现一定频率范围的正弦信号,由集成运放及外围电路实现的正弦电流源作为RLC并联电路的激励源.经调理电路可测定RLC并联电路的谐振频率、品质因数、通频带等主要参数.
The system was designed basing on AT89C51 microcontroller as the core,a certain frequency range sinusoidal signals from the DAC0832 and function generator ICL8038,sinusoidal current source output by an integrated amplifier and peripheral circuits,as the excitation source of the RLC parallel circuit.RLC parallel circuit＇s resonant frequency,quality factor,the pass band and other parameters can be determined by conditioning circuits.
