BIAS OF TRIANGULAR SIGNAL AMPLITUDE ESTIMATION USING THREE-PARAMETER SINE FITTING IN THE PRESENCE OF ADDITIVE NOISE

Triangular waveforms are widely used as stimulus signals in instrumentation and measurement, and their amplitude is frequently recovered by applying a least-squares sine-fitting algorithm to the signal’s Fourier fundamental. This paper examines the accuracy of that approach when the acquired samples are corrupted by ad...

On the Precision of Impedance Argument Estimation in the Presence of Additive Noise

Estimating the argument of an electrical impedance is an important task in many engineering fields. Modern systems usually employ data acquisition systems to sample and digitize the voltage and current signals obtained by stimulating the unknown impedance with a sinusoidal signal. The presence of nonideal phenomena in...
