Detection circuit and filter in the circuit experiment and test equipment in a very wide range of purposes. Based on frequency detection circuit and the principle of bandpass filter and structure analysis, design a differential frequency CCT circuit and 0 ~ 500KHz active low-pass filter circuits. Circuit consists of a differential LC oscillating circuit, a mixed time-frequency circuit and low pass filter circuits. To design the circuit testing experiment, obtains the different temperature low pass filter circuit amplitude frequency characteristics. Contrast circuit testing results, the differential frequency temperature detection circuit.
