Selecting Analog-to-Digital Conversion Parameters when Analyzing Noise in Track Circuits of Rail Traffic Safety Systems

详细

A technique is proposed for selecting analog-to-digital conversion parameters when analyzing noise in track circuits of rail traffic safety systems. Relations are obtained for estimating standard conversion errors for fluctuation, harmonic, and pulse noise. Relations are given for estimating conversion errors for typical random noise models. The maximum and time-averaged standard errors are considered with allowance for the dependence of the conversion error variance on the sample spacing.
