Abstract

Output frequency signal from the "physical quantity-to-frequency" (X/f) converter is often transmitted and converted in the slotted line with frequency carrier of information. This paper presents a meteorological analysis of a slotted line with frequency carrier of information, which obtain signal from the X/f converter. A changeable physical quantity conversion in the X/f converter causes a signal with changeable frequency generation. It is shown that the accuracy of the slotted line is determined by the construction-depending error of the X/f converter, the quantization error, the averaging error and the approximation error. Essential components of the total conversion error are the averaging error, the approximation error and the quantization error. Values of the approximation error and the averaging error are rising when signal frequency of the X/f converter output is decreasing. The quantization error value is rising when signal frequency of the X/f converter output is rising. Estimations of these errors are given. Ways of minimizing the total error are proposed.
