James Feher,”Introduction to Digital Logic” with Laboratory Exercises (2010)

This lab manual provides an introduction to digital logic, starting with simple gates and building up to state machines. Students should have a solid understanding of algebra as well as a rudimentary understanding of basic electricity including voltage, current, resistance, capacitance, inductance and how they relate to direct current circuits.
