Paper format. National Exams, December 2013 — 07-Elec-A3, Signals and Communications. Three hours, closed book (one two-sided aid sheet and an approved calculator permitted). Six questions, all of equal value at 20 marks; five constitute a complete paper.
All six questions are solved here. The examination marks only the first five answers submitted, but this document is a study resource, so every question — and every sub-part — is worked in full.
