Study guide for final: Revise negative numbers in binary system, conversion between hex-oct-dec-bin bases, addition, multiplication.
Drawing  circuit from expression or vice versa. Truth tables, minterms, k-map, decoder, mux, encoder, demux. Good luck.

Attention:   Here is the model answers to quizzes and midsemester exam.
