【摘要】 设计了一种由滤波器和迟滞比较器构成的传输频率信号电路。设计使用滤波器将输入信号改变适当的相位作为迟滞比较器标准端的信号,而原信号输入比较器的另一端。那么由于迟滞比较器标准端的电压同时随输入信号改变。电路对不同的信号有一定的适应能力。即对不同的输入信号,不需要另外确定标准端的电压。简化了电路,提高了可靠性。同时滤波器的加入使电路同时获得频率选择的能力。仿真证明了电路的可行性。更多还原

【Abstract】 This paper designs a circuit based on hysteresis comparator and filter which is used to transfer frequency signal.A filter is used to change the signal in appropriate phase for the filter′s input when the original signal for another.It could adjust the signal better because both of two ends of the hysteresis circuit connect to input and change with its changes.For the various inputs,we need not change the criterion voltage of the circuit.The circuit will be predigested.At the same time,as a filter in design,the circuit gets the(ability) of frequency selection.This design has been simulated to prove its feasibility.更多还原
