OUTCOMES:

A student WHO with success fulfills the course necessities can have demonstrated:
• a capability to outline completely different variety systems, binary addition and subtraction, 2’s
complement illustration and operations with this illustration.
• a capability to know the various switch pure mathematics theorems and apply them for
logic functions.
• a capability to outline the Karnaugh map for some variables associate degreed perform an recursive
reduction of logic functions.
• a capability to outline the opposite decrease strategies for any variety of variables
Variable Entered Mapping (VEM) and Quine-MeCluskey (QM) Techniques and perform
an recursive reduction of logic functions.
