Analysis of the single pion electroproduction data is one of the most powerful tools in investigating the nucleon resonances in the first and second resonance regions. Recent pion electroproduction experiments using CLAS detector at Jefferson Lab for the first time provides us with data for the cross sections and the single beam spin asymmetries for both epto e' n pi^+ and epto e' p pi^0 channels. In order to analyze this data an analysis program based on the Mainz unitary isobar model was developed at Jefferson Lab. The single pion electroproduction cross sections and the single beam asymmetry data were fitted simultaneously to obtain the resonant amplitudes for the excited states in the first two nucleon resonance regions. Preliminary results will be presented for the electroproduction amplitudes for the S_11(1535) and D_13(1520) resonances.
