Logical and Binary Systems, ANDOR, NAND-NOR Logic, Truth tables, Realizations Logical and Binary Systems ◠Digital circuits process signals that contain just two levels/states ○ Logic “0†■Logic “1†represents a higher voltage ■Typically referred to as a HIGH value ○ Logic “1†■Logic “0†represents a lower voltage ■Typically referred to as a LOW value ◠Each discrete voltage levels are referred to as Binary Digits or Binary BITS ◠Binary number system is a Base-2 number system ○ Follows the same rules as other mathematical systems like Base-10 ○ For example: ■Instead of powers of ten (10????) binary numbers use power of two (2????) ANDOR ◠This acronym represents two logic gates ○ AND ○ OR ◠AND gate ○ If 0 is called
