Chapter 3 Flashcards
a number to be divided by another number.
DIVIDEND
a number by which a dividend is divided.
DIVISOR
the number obtained by division
QUOTIENT
part of a dividend that is left over when the dividend is not evenly divisible by the divisor.
REMAINDER
BCD
Binary Coded Decimal
When a decimal number is represented by its equivalent binary, we call
it —————————–. But if each digit of a decimal number is represented by its binary equivalent, the result is —————————–
Straight Binary Coding, Binary Coded-Decimal
Representing Decimal number in its binary equivalent in BCD code requires ———- bits on each digit.
FOUR
is a weighted code that is commonly used in digital systems when it is necessary to show decimal numbers such as in digital clock displays.
Binary coded decimal (BCD)
also known as Gray code
reflected binary code
is a binary numeral system where two successive values differ in only one bit.
Gray code
Gray code is designed by after
Frank Gray and patented in 1953
The reflected binary code was originally designed to prevent spurious output from ————————–.
electromechanical switches
Today, Gray codes are widely used to facilitate —————— in digital
communications such as digital terrestrial television and some cable TV systems.
error correction
It is an —————– code that has a ——— bit change between one code word and the next in a sequence
gray code
unweighted, single
is used to avoid problems in systems where an error
can occur if more than one bit changes at a time.
Gray code
Floyd on its book ——————– gives an example of a ———————– as a typical application of using gray code generator.
digital Fundamental, shaft encoder
This sensor detects the presence and absence of colors.
three IR emitter/detector
Light color represents “————” and darker color represents “—————”. The light color gives use good reflection while the dark color gives poor reflection.
logic 1, logic 0
The Gray code is used in applications where numbers change rapidly. In gray code only one bit changes from each value to the next. This system eliminates the potential errors
readings only
Binary to Gray code conversion method strongly follows the operation of ————
Exclusive-OR gate.
XOR
