Abstract
A method for the measurement of the membrane capacitance and resistance with two simultaneous sinusoidal frequencies is described. This method combines the advantages of measurements with a single sinusoidal frequency (i.e. low noise - high resolution) and those with rectangular waveform or polyfrequent methods. The mathematical analysis of the impedance as well as the admittance are presented for the evaluation with synchronous detection. Preliminary results are given.
