This paper presents a Built-In Test (BIT) scheme intended for detection of nonlinearities, classification of the form of nonlinearity and evaluation of the total harmonic distortion (THD) of the signal under test, without using expensive automatic test equipment (ATE). The tester is based on a sigma-delta modulator located on a board and artificial neural networks implemented in an attached personal...
This paper presents a build-in self-test (BIST) scheme intended for the extraction of diagnostic information from the analog signal coming from oscillation-based test application. Based on the sigma-delta modulation technique and artificial neural networks the proposed scheme can detect nonlinearities, classify the form of nonlinearity and evaluate the total harmonic distortion (THD) of the signal...
