DIGITAL ELECTRONICS - U1-U2

This is the numerical system used by digital systems to count and is the code to which it translates all the information it receives. The electrical impulses that circulate in the circuits are low or high voltage, the bistable switches are on or off, open or closed, etc.

• Decimal system

• Binary system

• Octal system

• None of the above options

Code is a special type of binary code that is not weighted (the digits that make up the code do not have an assigned weight). Its main applications are in the industry and in robotics. In robotics, encoded discs are used to give the position information that a particular axis has.

• GRAY code

• ASCCI code

• BCD code

• None of the above options

GATE LOGIC:

• NAND

• OR

• AND

• NEITHER

TRUTH TABLE:

• OR EXCLUSIVE

• OR

• NOR

• NEITHER

BOOLEAN EXPRESSION:

• AND ; OR

• OR ; XOR

• NAND ; NOR

• NEITHER

Its algebraic expression is X = X ’, This gate is basically an inverter, it only has one entry, if at the entrance we have a high state, the exit reverses it and converts it to low.

• NOT

• NOR

• XNOR

• NEITHER
