Lecture
This lecture covers Thevenin equivalent circuits, A/C and oscillatory signals, generalized impedance, capacitors, and filters. It starts by explaining how to find an equivalent circuit with a voltage source and a resistance for any two nodes in a linear circuit. Then, it revisits the voltage divider concept and introduces the Thevenin equivalent circuit and output impedance. The lecture proceeds to discuss reactive circuit elements, focusing on capacitors and their transient responses. It delves into the concept of impedance, reactance, and generalized impedance for capacitors. Finally, it explores frequency-dependent responses and filter devices, such as low-pass, high-pass, and band-pass filters.
