What is the BCD 8421 representation of?

In other words, the BCD is a weighted code and the weights used in binary coded decimal code are 8, 4, 2, 1, commonly called the 8421 code as it forms the 4-bit binary representation of the relevant decimal digit.

How do you convert from hex to binary?

How to Convert Hex to Binary

1. Step 1: Write down the hex number.
2. Step 2: Each hex digit represents four binary digits and therefore is equal to a power of 2.
3. Step 3: Determine which powers of two (8, 4, 2 or 1) sum up to your hex digits.
4. Step 4: Write down 1 below those 8, 4, 2 and 1’s that are used.

What is the first step in converting a decimal number to binary?

Converting decimal integer to binary To convert integer to binary, start with the integer in question and divide it by 2 keeping notice of the quotient and the remainder. Continue dividing the quotient by 2 until you get a quotient of zero. Then just write out the remainders in the reverse order.

How do you write 13 in binary?

Therefore, 13 can be written as a binary system as 1101.

What is the value of 1 1 in binary addition?

In binary addition, 1+1+1 is 11. As, 1 + 1 is 10, and further if we add 1, we get, 10 + 1, which is equal to 11.

How to convert 4 bit binary to hexadecimal?

So, if you make each group of 4 bit of binary input number, then replace each group of binary number from its equivalent hexadecimal digits. That will be hexadecimal number of given number.

How to represent any digit of hexadecimal number system using only 4 bits?

Since, there are only 16 digits (from 0 to 7 and A to F) in hexadecimal number system, so we can represent any digit of hexadecimal number system using only 4 bit as following below. So, if you make each group of 4 bit of binary input number, then replace each group of binary number from its equivalent hexadecimal digits.

How to convert binary number 1101010 into hexadecimal?

Example − Convert binary number 1101010 into hexadecimal number. First convert this into decimal number: = (1101010) 2 = 1×2 6 +1×2 5 +0x2 4 +1×2 3 +0x2 2 +1×2 1 +0x2 0 = 64+32+0+8+0+2+0 = (106) 10 Then, convert it into hexadecimal number = (106) 10 = 6×16 1 +10×16 0 = (6A) 16 which is answer.

How do you convert binary numbers to words?

Making Basic Conversions Find a line of up to four binary numbers to convert. Write a small “1” above the last digit. Write a small “2” above the third digit, a “4” above the second, and an “8” above the first. Count out how many of each “place” you have. Add your four numbers together. Change any number above “9” into a letter.
