Objective of the course is to make everyone design a digital circuit efficiently using various components.

Digital systems contain information that is represented as binary digits called bits.

The alphabet of these bits is the set {0, 1}, which represents the logical value of the

bits. The physical value is determined by the logic family being used. The transistor-transistor

logic (TTL) family represents a logic 0 typically as + 0.2 volts and a logic 1

typically as + 3.4 volts using a + 5 volt power supply; the emitter-coupled logic (ECL)

100K family represents a logic 0 typically as – 1.7 volts and a logic 1 typically as –0.95

volts using a – 4.5 volt power supply.

Thus, a signal can be asserted either positive (plus) or negative (minus), depending

upon the active condition of the signal at that point. The word positive, as used

here, does not necessarily mean a positive voltage level, but merely the more positive

of two voltage levels, as is the case for ECL.
