A digital demodulator based on the recursive Gauss-Newton method for electrical tomography

Abstract

In the paper, a digital demodulator based on the recursive Gauss-Newton method is proposed for Electrical Tomography. The digital demodulator can track the amplitude and phase of a noisy sinusoidal signal with known frequency directly. Compared with the traditional digital multiplication demodulation method, the proposed demodulator is more flexible. It is… (More)
