Prerequisites: familiarity with Resistance, Capacitance, Electric current, Kirchhoff's rules, DC circuits and AC circuits. The course covers the fundamentals of the lumped circuit abstraction. The main contents are: independent and dependent sources; Resistive circuits RC, RL and RLC circuits in time domain and frequency domain; Impedance transformations; Two-port networks and parameters Operational amplifiers Filters, Diodes and Transistors. Small signal and large signal analysis. Includes a weekly laboratory.
