Popis:	In this paper, we present a novel time domain technique for measuring the relative permittivity e r of samples based on pseudonoise test signals (M-sequences). Analog correlation is the key enabler of our system, providing high time resolution while minimising the effort required for sampling. Moreover, a linear error model is proposed and the system's measurement uncertainty is assessed. A comparison with reference measurements of PTFE samples concludes this paper.
