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