22-Mec-A3 System Analysis and Control: December 2013

Paper format. National Exams, December 2013 — 07-Mec-A3 System Analysis and Control. Three hours, closed book; a Casio or Sharp approved calculator and semi-logarithmic graph paper are the only permitted aids. Six questions are printed; the rubric states that any four questions constitute a complete paper and that all questions are of equal value. A two-page table of Laplace transform pairs is appended to the examination. Because this set is a study resource, all six questions are solved in full below.
