Paper format. National Exams May 2019, 16-Elec-B5 Advanced Electronics — 3 hours, CLOSED BOOK, one approved Casio or Sharp calculator. Five questions, all to be answered, 20 marks each (100 marks total). In schematics ground and chassis are common; op-amps are ideal and supply rails are ±15 V unless stated otherwise. Candidates are told to state any interpretive assumption inside the answer, and to supply block diagrams and schematics wherever an essay-format response needs them.

How each answer is laid out. Every question states its data, the quantity sought, the circuit as drawn on the paper, a one-line strategy, then numbered steps carrying the governing relation, the substitution and the intermediate result. Boxed values are the answers a marker looks for, and each question closes with a results table and a concept note.
