Abstract: A network correction security system. The network correction security system connected between a network node and a security-related external system, detects attacks on the network node, corrects weak parts of the performance of the network node, collects information for improving the security performance of the network node from a security-related external system, analyzes the information, monitors principal resources of the network node to detect a fault, and removes the fault according to a measure corresponding to a grade of the fault. The network correction security system carries out a recovery process when the fault has not been corrected, and recovers the functions of the network node according to a recovery mechanism when the fault has not been removed after the recovery process.

Abstract: The present invention relates to a scheme for simply implementing a demodulation circuit, which is a core circuit of a measuring instrument, using a lock-in detection method. The present invention provides a signal demodulation circuit includes an inverting amplifying circuit and a low pass filter circuit. The inverting amplifying circuit has an operational amplifier with a disable function. The low pass filter circuit is electrically connected to an output terminal of the inverting amplifying circuit to output a signal wave. Accordingly, the present invention provides a signal demodulation circuit, which has a simplified construction, thus reducing the size of the circuit, enabling a demodulation circuit to be implemented when a multi-channel signal is processed or when circuit space is limited, and greatly reducing production costs and power consumption.
