Number Systems and Codes Questions

• 3428 is the decimal value for which of the following binary coded decimal (BCD) groupings?
• What is the decimal value of the hexadecimal number 777?
• Convert the binary number 1001.0010 to decimal.
• The weight of the LSB as a binary number is:
• What is the result when a decimal 5238 is converted to base 16?
• Convert the decimal number 151.75 to binary.
• The number of bits used to store a BCD digit is:
• Base 10 refers to which number system?
• Sample-and-hold circuits in ADCs are designed to:
• Convert the binary number 1011010 to hexadecimal.
• Convert 110010012 (binary) to decimal.
• What is the difference between binary coding and binary coded decimal?
• What is the resultant binary of the decimal problem 49 + 1 =?
• ASCII codes are used strictly for representing the letters in the alphabet.
• In the gray code, each number is 3 greater than the binary representation of that number.
• When using the excess-3 code a value of 3 is added to each column of decimal digits before it is converted to a 4-bit binary code.
• The process of converting a decimal number to its binary equivalent is called binary conversion.
• The most significant digit is the rightmost, largest-weight digit in a number.
• If you borrow from a position that contains a 0, you must borrow from the more significant bit that contains a 1. All 0s up to that point become 1s, and the digit last borrowed from becomes a 0.
• Decimal numbers can be converted into binary by dividing by two and recording the remainders.
