Answer 1

Answer:

option (a)1001 I am not sure

Answer 2

The largest 4-bit binary number used in the BCD co.de is 1001. (Option A)

• In this system, each decimal number is enco.ded by a 4-bit binary number.
• A binary number is used to represent each decimal digit in BCD.
• We can express sixteen numbers with four bits in BCD (0000 to 1111).
• The BCD co.de, however, only uses the very first ten of them (0000 to 1001).
• The last six BCD co.de options, 1010 to 1111, are erroneous.
• BCD Co.des have the advantage of being quite close to the decimal system, and we just need to understand the binary counterparts of the decimal digits zero to nine.
