22-Elec-B5 Advanced Electronics: December 2014

Paper format. National Exams, December 2014 — 07-Elec-B5, Advanced Electronics. Three hours; closed book; any non-communicating calculator permitted. Answer all FIVE (5) questions, each worth 20 marks. The paper instructs candidates to state clearly any assumptions made where a question admits more than one interpretation, to start each question on a new page, and to assume that ground and chassis are common and that op amps are ideal.

All five questions on this paper are calculation questions built on a circuit schematic, so each is worked in the standard Given → Find → Figure → Approach → Steps → Results shape. Every schematic below was redrawn from the printed figure; where the printed drawing decides an answer, the reading taken is stated explicitly in a callout.
