Expectation Maximization Principal Component Analysis

The simulation experiment is based on Candence 16.6 software, where the tolerance of the resistance (R) is set to 5%, the tolerance of the capacitance (C) is set to 10%, the input is a single-pulse signal (amplitude 5 V, pulse width 10 µs, eriod 2ms), and the working temperature is set to 27 ℃. The operational amplifier(op-amp) uses the actual UA741 pspice model. The experiment includes the soft fault diagnosis of Sallen-Key band-pass filter circuit (TC1), Four-op-amp biquad high-pass filter circuit (TC2), and Leap-frog low-pass filter circuit (TC3).
