Perform the following bit operations:   A)  1 OR 0   B)  0 XOR 0   C)  1 AND 1   D)  NOT 1   E)  1 NAND 0

The range of values of a 2-byte signed two's complement value is: -128 to 127 O -1,024 to 1,023 -32,768 to 32,767 -65,536 to 65,535

Define Data bits.

5. Using MATLAB, input a binary bit sequence and plot the unipolar-nrz signal.

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?
