Embodiment 1
[0011] Embodiment 1. A service management system based on big data, including a signal sampling module and a separation and noise reduction module. The signal sampling module uses a signal sampler J1 model DAM-3056AH to process node signals in the big data service management system. Sampling, the separation and noise reduction module uses the operational amplifier AR1 and the transistor Q1 to form a synchronous separation circuit to separate the signal into two signals of different amplitudes, and one way uses the operational amplifier AR2, the operational amplifier AR4 and the transistor Q4 to form a noise reduction circuit filter In addition to the phase noise interference in the signal, the second circuit uses transistor Q2 and transistor Q3 to form a push-pull circuit to prevent signal crossover distortion, and uses the op amp AR3 to compare the signals, in which the triode Q5 feeds back a high-level signal to the op amp AR1 and op amp AR1. The inverting input terminal of t...
