To improve the investigation into the interaction between protein channels and different kinds of electromagnetic signals, techniques for the analysis of ionic currents in the frequency domain are required. In this paper, the authors propose an analytical expression for the power spectral density of stochastic processes generated by Markov models of ionic channels. This approach enables us to overcome limitations due to long times of simulation necessary for obtaining a good spectral estimate. Moreover we can calculate the spectrum of simulated currents independently from model implementations so that the obtained result may be considered as a reference solution.
