BCD-BinaryCodedDecimal->Binary equivalent of each decimalexpressed using 4 bits->For single digit decimal BCD is same as its binary.In BCD only first 10 binary numbers are valid.The remaining 5 are invalid. Gray code is an unweighed code. ex: G3=B3 G2=G3 XOR B2 G1=G2 XOR B1 G0=G1 XOR B0


A 4 BCD code is a 4 decimal-digit BCD code, thus a 16 digit binary-code. You take the decimal number 3545. It's BCD code is 0011 0101 0100 0101 where every 4 bits represent a decimal digit.



I will answer this by example: BCD is unweighted code, XS3 is weighted by 3 code. 0 in BCD 0000, XS3 0011 1 in BCD 0001, XS3 0100 2 in BCD 0010, XS3 0101 3 in BCD 0011, XS3 0110 4 in BCD 0100, XS3 0111 5 in BCD 0101, XS3 1000 6 in BCD 0110, XS3 1001 7 in BCD 0111, XS3 1010 8 in BCD 1000, XS3 1011 9 in BCD 1001, XS3 1100


i dont know 1001+1001 - Constructing a BCD-to-excess-3-code converter with a 4-bitt adder we know that the excess-3 code digit is obtained by adding three to the corresponding BCD digit. To change the circuit to an excess-3-to-BCD-code converter we feed BCD-code to the 4-bit adder as the first operand. Then feed constant 3 as the second operand. The output is the corresponding excess-3 code. To make it a BCD to excess-3 converter, we feed the 2's complement of 3 as the second operand. - Constructing a BCD-to-excess-3-code converter with a 4-bitt adder we know that the excess-3 code digit is obtained by adding three to the corresponding BCD digit.

we converter BCD to EXCeSS-3 is first rule 2 4 2 1 and other third number of BCD add other BCd as 0 to 15 Type your answer here...


The decimal number 10, represented in BCD is 0001 0000. If, instead, you mean that you have 10 in BCD and want to know what that means, that is equivalent to 0000 0010 and would be 2 in decimal.


4 full adders will be used BCD is a 4 bit code. Each bit of the BCD number will be an input of each full adder. input 1 in first FA. 1 in second and 0 in the last to FA's


32251 is an invalid CPT code


check this link for the code:http://www.dnatechindia.com/index.php/Code-Library/8051_ASSEMBLY/12-bit-HEX-to-BCD-Convertor.htmlhttp://www.dnatechindia.com/index.php/Code-Library/8051_ASSEMBLY/8-bit-HEX-to-BCD-convertor.htmlA: The conversion is simple really a group of FOUR bits are usually the best method to simplify a BCD of four bits in hexadecimal. Example 1111 is just written F If it was written in octal the bits will be 3 as 111 or 7. As BCD becomes longer and longer these two methods were used to simplify the code a128 bits in BCD will be 8 zeros and ones or simply FF in octal notation it becomes 277


A: A Binary code represent a binary number 0.1.2.4.8. etc. that is why it is called a weighted number



BCD codes,gray code,error detecting code,ASCII character code,Excess 3 code


A: A BCD code must be decoded to provide a seven digit output to the 7 bars display that is the only way to see the binary number visually.



BCD refers to Binary Code Decimal there are no diagrams it is just a numbers system GRAY code is a means to make one reliable state to change at a time eliminating false coding because of transitions in counters and such


Well, with a BCD to gray code converter, of course.However as gray code deliberately has no coding glitches and BCD has multiple coding glitches, designing such a converter without introducing coding glitches in the gray code is more difficult than might be imagined. The 6 missing binary codes in BCD are also a significant issue in trying to convert to gray code, as no missed values are permitted.A coding glitch can occur at any time more than one bit of the code changes to go to the next (or previous) sequential value.

You're in the wrong department, buddy.


In The Name Of GOD... To convert from exs-3 to BCD it is obvious that you will subtract 3 from each number in excess-3 code; Ex: to convert 1001 in excess-3 to BCD you will subtract 3=0011 from it so output is 0110... HINT: for all digits>9 it is forbidden to convert to BCD... so you will have to convert from 0000 to 1001 only. For any discussing contact me: ahmed_gad20102@yahoo.com


Decimal 30 = binary 11110. The decimal binary code (BCD), however, is 11 0000.



In BCD each digit of a decimal number is coded as a separate 4 bit binary number between 0 and 9.For example:Decimal 12 in BCD is shown as 0001 0010 (Binary 1 and Binary 2), in Binary it is 1100.


Country code +7 is Russia and Kazakhstan, but +7 27 is an invalid code.
