Introduction to Digital Electronics

Number Systems and Codes:- Binary, Decimal , Octal, Hexadecimal and their inter-
conversions, Codes:- BCD, Excess-3, Gray code etc. 

Digital electronic signals and switches: - Concept on digital signal, logic levels, Active
high,   Active   low   signals,   Switching   Characteristic   of   Semiconductor   diode,
Transistor. 

Logic Gates: - AND, OR, NOT, NOR, NAND, EX-OR, EX-NOR operations and their
truth  table.    Boolean  algebra  and  reduction  techniques:  -  K-Maps  and  Quine  –
McClusky.
