- Exercise 1: (1) Devise simple but non-trivial circuits to show at least five different ways to formulate state equations. Try to use similar circuits for the five different formulations. (2) Devise a simple but non-trivial circuit with one or more loops of capacitors. Express its state equation. (3) Devise a simple but non-trivial circuit with one or more cuts of inductors. Express its state equation. (4) Devise a method to formulate circuits with branch voltage sources using nodal analysis. Describe the conditions that the nodal analysis formulation is feasible.
- Exercise 2: For matrix computations using iterative methods, according to the formulations of minimal error in A norm and minimal residual, derive the procedure of a) Lanczos, b) conjugate gradient, c) GMRES, and d) conjugate residual. (1) Describe the algorithm of the procedure. (2) Use a 5x5 matrix to demonstrate your algorithm using Krylov space of dimension two, i.e. K(r,A,2). (3) Discuss the error in the example due to the limit of the dimension of Krylov space. (4) Discuss the error in the example due to the numerical error.
- Exercise 3: Use Tellegen's theorem to prove the reciprocal theorem in (1) frequency domain and (2) in time domain. State the conditions for nonlinear systems.
