National Exam — 07-Elec-A5 Electronics — December 2016. Closed-book; any non-communicating calculator permitted; three hours. Five questions, 20 marks each — all five constitute a complete paper, so every question is solved below. Per the paper’s notes, op-amps are ideal with supply rails of ±15 V unless a question states otherwise, and ground/chassis are common.
