1. A method of determining a resistance in an electric circuit, the method comprising:
applying a voltage pulse to a test point of said electric circuit using pulse injection, said voltage pulse having a predetermined pulse duration;
measuring an electric observable at a response point of said electric circuit during at least a part of said pulse duration;
estimating during said pulse duration an expectation value from said measured electric observable by fitting measured values of the measured electrical observable to a predetermined model; and
determining said resistance from said expectation value,
wherein:
the electric observable is voltage and current; and
the predetermined model is an exponential model.
