资料介绍

针对传感器频率特性频宽较窄的问题,设计并实现了一种高效简易的频率补偿电路,使用与传感器频率特性传递函数成互倒关系的均衡器电路实现对传感器的频率补偿,并用低通滤波的方式进行修正。设计电路主要由模拟传感器频率特性电路、均衡器电路和低通滤波电路组成,经过理论的计算和实际参数的调试测量,设计电路将传感器电路的截止频率从4.5 kHz提高到了100 kHz,且输出信号稳定性好,整个电路功耗低、噪声小,具有较高的性能指标。

An efficient and simple frequency compensation circuit is designed and implemented to solve the problem that the sensor always has a narrow bandwidth of frequency.The system uses an equalizer circuit with the transfer function of frequency characteristic inverse to that of the sensor circuit to achieve frequency compensation and is corrected by low-pass filtering.The design circuit includes a frequency characteristic circuit of the analog sensor,the equalizer circuit and the low-pass filter circuit.Through theoretical calculations and actual debugging,the cutoff frequency of sensor circuit is successfully increased from 4.5 kHz to 100 kHz.The circuit has high performance indicators for its stable output,low power consumption and low...
