Abstract
In time-domain, it is hard to calculate the voltage and current distributions along the distributed parameter transmission lines with a low sampling frequency. The algorithm of linear interpolation is introduced to calculate the voltage and current along the lines, and the appropriate frequency band and its affected factors is analyzed by comparing the theoretical and practical error. Simulation results show that, for the fixed sampling frequency, the error rises with the frequency increasing of periodic signal, and decreases with the attenuation time constant increasing of non-periodic signal. The sampling frequency determines the upper limit of appropriate frequency band directly. The research provides the basis for the selection of cutoff frequency in filter design.
