How many bits are required in decimal numbers in range 0 to 999 using Straight binary code and BCD code?
10 bits would be required. 10 bits long (10 digits long) can represent up to 1024.
Explain binary coded decimal?
Binary Coded Decimal (BCD) is a set of coding systems for storing decimal digits in binary code. There are several such codes, I will give examples of 3: straight BCD, XS3 BCD, and 2 of 5 BCD. Straight BCD uses the actual binary value of the decimal digit value: 0 = 0000 1 = 0001 2 = 0010 3 = 0011 4 = 0100 5 = 0101 6 = 0110 7 = 0111 8 = 1000 9 = 1001 XS3 BCD adds 3 to the binary value of the decimal digit value to make the code: 0 = 0011 1 = 0100 2 = 0101 3 = 0110 4 = 0111 5 = 1000 6 = 1001 7 = 1010 8 = 1011 9 = 1100 2 of 5 BCD uses a 5 bit code where only 2 bits can be on in a decimal digit's code: 0 = 00011 1 = 11000 2 = 10100 3 = 10010 4 = 10001 5 = 01100 6 = 01010 7 = 01001 8 = 00110 9 = 00101
How will bcd convert into 7segment display?
BCD can be converted into 7segment display by using an encoder.
What is the difference between weighted and non weighted codes?
what is weighted codes: The decimal value of a code is obtained summing up the positional values. weghted binary code s are those which obey positional weighting principle. each position of number represents a specific weight. There are millions of weighted code The most common one is 8421 Non weighted codes: This codes are not positionaly weghted. each position with in the binary no is not assgned to afixed value.Examples of nonweghted code is ASCCI, GREY CODE, EBCDIC CODE etc
What is the count sequence for a BCD down-counter?
The count sequence of a BCD down counter is as follows: 1001,1000,0111,0110,0101,0100,0011,0010,0001,0000,1001. . . . . . .
Write an alp to convert a 2 bit number from BCD to binary?
All possible 2-bit numbers ... 0, 1, 2, and 3 ... are the same in BCD and binary. No conversion is required.
What is deference between BCD and decimal number?
BCD is a decimal number. BCD is one specific way to store decimal numbers in computer memory.
What are the advantages of bcd code?
advantages of bcd codes:-- it combine all basic numbers- it is easilly understand by human beings
What are ASII and BCD how are they used?
ASCII (American Standard Code for Information Interchange) and BCD (Binary Coded Decimal) are standards for storing information in the binary sytem. ASCII is used for storing alphabetic, numeric, symbols, and control characters in 8-bit binary, and BCD is used for storing numbers 0-9 in 4-bit binary.
How does BCD differ from the straight binary number system?
To consider the difference between straight binary and BCD, the binary numbers need to be split up into 4 binary digits (bits) starting from the units. In 4 bits there are 16 possible values from 0000 to 1111 (0 to 15). In straight binary all of these possible combinations are used, thus: 4 bits can represent the decimal numbers 0-15 8 bits can represent the decimal numbers 0-255 12 bits can represent the decimal numbers 0-4095 16 bits can represent the decimal numbers 0-65535 etc In arithmetic, all combinations of bits are used, thus: 0000 1001 + 0001 = 0000 1010 In BCD or Binary Coded Decimal, only the representations of the decimal numbers 0-9 are used (that is 0000 to 1001 in binary), and the 4-bits (nybbles) are read as decimal digits, thus: 4 bits can represent the decimal digits 0-9 8 bits can represent the decimal digits 0-99 12 bits can represent the decimal digits 0-999 16 bits can represent the decimal digits 0-9999 In arithmetic, only the representations of decimal numbers are used, thus: 0000 1001 + 0001 = 0001 0000 When BCD is used each half of a byte is read directly as a decimal digit. BCD is obviously inefficient as storage (for large numbers) as each nybble is only holding 3/8 of the possible numbers, however, it is sometimes easier and quicker to work with decimal digits (for example when there is lots of display of counting numbers to do there is less binary to decimal conversion needing to be done).
Why is BCD used in computers?
BCD is used for binary output on devices that only display decimal numbers.
What number is between 0 and 20?
There is an infinite number of numbers between 0 and 20.
What range of numbers may be held in a nibble?
4 bits range of number. At most, this covers the range from 0 (zero) to 15 (fifteen) when encoded as binary numbers. However, some number systems exist that encode using a less compact scheme. BCD, short for binary coded decimal, doesn't use the A...F range of the hexadecimal system. For BCD numbers, a nibble only holds values 0 (zero) to 9 (nine).
What are the prime numbers 0-20?
The prime numbers 0-20 are 2, 3, 5, 7, 11, 13, 17, and 19.

What are the prime numbers between 0 and 20?
The prime numbers between 0 and 20 are: 2, 3, 5, 7, 11, 13, 17 and 19
