  2. CIRCUIT ANALYSIS TOOLS: MATLAB, PROTEUS • MATLAB • Circuit schematic • 2ne equations/unknowns • MATLAB solutions • PROTEUS • Circuit schematic • Voltage, current probes • Voltage current waveforms Ertuğrul Eriş

  3. MATLAB OBJECTIVES • TO USE MATLAB TOOLS FOR CIRCUIT ANALYSIS • V-I relations (Definition relations) • One variable functions plot • V=Ri, V=Ri, I=(1/R)*v; I=(1/R)*v • Plot(i,v) Ertuğrul Eriş
