QUOTIENT The result in division.
RADIX POINT The symbol that separates whole numbers and fractional numbers.
RADIX The total number of symbols used in a particular number system.
REGISTER A circuit of flip-flops designed to receive, store, and transfer data.
REMAINDER The final undivided part that is less than the divisor.
RING COUNTER A loop in which only one flip-flop will be set at any given time; used in timing.
RIPPLE (ASYNCHRONOUS) COUNTER A circuit that counts from 0 to a specified value. Subject to error at
high frequency.
R’s (RADIX) COMPLEMENT The difference between a given number and the next higher power of the
number system (10008 minus 2548 equals 5248).
R’s-1 (RADIX-1) COMPLEMENT The difference between a given number and the highest value symbol in the
number system (7778 minus 2548 equals 5248).
R-S FLIP-FLOP A flip-flop with two inputs S (set) and R (reset). The Q output is HIGH in the set mode and
LOW in the reset mode.
SERIAL DATA All data bits are transferred one bit at a time along a single conductor.
SHIFT REGISTER A register capable of serial-to-parallel and parallel-to-serial conversion and scaling.
SHIFTING Moving the contents of a register right or left to scale the number or to input or output serial data.
SUBSCRIPT A number written below and to the right of a value indicating the base or radix of the number
system in use (358).
SUBTRACTION Taking away one number from another.
SUBTRAHEND The quantity to be subtracted from the minuend.
SUM The result in addition.
SYNCHRONOUS COUNTER Performs the same function as a ripple counter but error free at high frequency.
T FLIP-FLOP A single input flip-flop that changes state with each positive pulse or each negative pulse. Divides
input frequency by two.
TRUTH TABLE A chart showing all possible input combinations and the resultant outputs.
UNIT A single object.
UP/DOWN COUNTER A counter circuit that can count up or down on command.
VINCULUM A bar over a logic statement indicating the FALSE condition of the statement.
WHOLE NUMBER A symbol that represents one or more complete objects.
ZERO A symbol that indicates no numerical value for a position in positional notation.
