3. b) What is the result of scrambling the sequence 11100000000000 applying each of the following scrambling techniques? Assume that the last non-zero signal level has been positive. a)B8ZS b) HDB3 (The number of nonzero pulses is odd after the last substitution.). *

In single precision (IEEE-754 standard), 8 bits are used for storing the exponent (the bias is 127), and 23 bits are used for storing the mantissa.  (a) What are the smallest and the largest positive numbers that can be stored in single precision? (b) What is the smallest value of the mantissa that can be stored?

6. For an 8-bit operand, specify the 8-bit mask and the logical operator to perform the following operations. Bit positions are numbered 7-0, left to right. a. Logical Operator: Logical Mask: b. Set all bits to 1. Logical Operator: C. Clear bits 5, 4, 3, and 2 to 0. All other bits remain unchanged. Logical Mask: d. Complement bits 2, 1, and O. All other bits remain unchanged. Logical Operator: Logical Mask: Set bits 7, 6, and 5 to 1. All other bits remain unchanged. Logical Operator: Logical Mask:
