“…Such an equation, even for linear systems, is nonlinear, and its solution requires the application of appropriate numerical procedures. This problem does not exist in the approaches devoted to detecting or classifying defects belonging to predefined classes [9,18,21,31,35]. A sketch of the diagnostic procedure, which proposes using the integer algorithm concept described in the previous sections, is presented below.…”

This paper presents an efficient numerical method to solve systems of nonlinear algebraic equations. The method uses a homotopy simplicial approach associated with an integer algorithm. The integer algorithm is discussed in detail and supplemented with original procedures that play an essential role during computation. The fundamental problem of initial simplex generation was solved using the bounded variable simplex optimization method. Efficient root finding of nonlinear equations has wide applications in numerical mathematics and various engineering problems. The proposed method was applied to solve nonlinear equations that arise during the diagnostics of multiple parametric faults in electronic circuits. Circuits made with surface mount technology were considered, as well as circuits designed in complementary metal-oxide-semiconductor and bipolar technology. A universal diagnostic procedure enables testing different circuit classes using standard measurement equipment. Laboratory and numerical experiments demonstrate that the proposed diagnostic procedure is effective.

“…Through the analysis of the time-domain response signal, the disguised fault diagnosis of the circuit can be realized. In continuous time systems, the impulse is modeled as a Dirac delta function and it is theoretically a short time pulse with infinite peak values [28]. Therefore, the impulse signal with the period of 1ms and pulse width of 10µs is chosen as the excitation signal in this paper.…”

Fault diagnosis techniques for analog circuits are widely applied in the diagnosis of electronic devices. It is of great significance to accurately and quickly find the fault location and the deviation of fault parameters in analog circuits. In this paper, we propose an innovative fault diagnosis approach for analog circuits. In this method, the wavelet packet transform (WPT) is employed to preprocess the time-domain response signals of analog circuit, and the proposed multi-channel one-dimensional residual networks (MC-1D-ResNet) is utilized for feature mining and fault diagnosis. Specifically, the two-level WPT is first carried out on the measured time-domain response signal to generate one approximate signal and three detailed signals. Additionally, the MC-1D-ResNet is developed by introducing a multi-channel structure based on 1D-ResNet, which can excavate and fuse various features from response signals and realize fault diagnosis. Through the simulation of the Sallen-key bandpass filter circuit and Four-opamp biquad high-pass filter circuit, the diagnostic reliability of this method has been fully verified. The results show that this method is very valuable for diagnosing faults of analog circuits and performs well on both test circuits. Even in the complex Four-opamp biquad high-pass filter circuit, the diagnostic accuracy can be up to 99.74%.
