14-page printable revision book covering the full syllabus path from foundations to TTL/CMOS.

Suggested study path

  1. Skim the syllabus — know which chapters carry 10 marks (Combinational, Registers/Counters, Sequential Machines).
  2. Read Theory Short chapters for fast coverage + solved mini-examples.
  3. Deep-dive weak chapters in Gemini HTML (or ChatGPT PDF for print).
  4. Drill repeated designs: sequence detectors, sync/async counters, SIPO/PISO, K-map, MUX adder/subtractor.
  5. Solve all 4 PQAs with the Claude answers — then redo without looking.
