Digital-designer shorthand notation for Boolean operators
ab
a + b
a’
function
a relation of an input’s values to an output’s values. A function must input all possibilities.
Digital circuits are sometimes called BLANK because of the roots in Boolean algebra’s logic operations of AND, OR, NOT
logic circuits
Expression
lacks an equal sign and involves input variables
ex. ab
Equation
has an “=”, with expressions of input variables on the right and an output variable on the left.
ex. y = ab
Binary uses a base of
2
Octal uses a base of
8
Hexadecimal uses a base of
16
Decimal uses a base of
10
Each number in binary is called a BLANK
bit
Overflow
occurs when the result of a binary operation is too large to fit in allowed number of bits
unsigned binary number
can only represent non-negatives values
signed binary number
uses the leftmost bit to represent whether a number is positive or negative
Valid digit symbol in octal:
0-7
Valid digit symbols in binary:
0-1
Valid digit symbols in hexadecimal:
0-15
Byte
A string of 8 bits
Character
a letter, symbol, or single-digit number
ASCII
popular code for characters
ASCII stands for
American Standard Code for Information Interchange
Unicode
Character encoding standard. Has more bits than ASCII
%d displays as
