The book will help students gain practical knowledge in using software to analyse and design linear circuits. Each chapter consists of a brief introduction followed by a series of carefully chosen examples. Every example uses a six step problem solving strategy: a) Formulate a circuit analysis problem. b) Describe the circuit as a LTspice schematic. c) Simulate the circuit using LTspice d) Display the results of the simulation. e) Verify that the simulation results are correct. f) Report the answer of the circuit analysis problem.
