7. Increasing or decreasing the number of pixels per inch changes the a. codec b. amplitude c. resolution d. color depth True or False (Circle either Tor F, 5 points each) 8. T F A multiplexer can have 4 input signals and output 1 or 2 signals at a time. 9. T F A register is commonly made up of d-latches to store bits. I 10. T F The largest positive number that can be represented in n bit signed form is 2"-1 11. T F The combination of numbers that adds up to a result outside the range is known as an overflow 12. T F JPEG is a popular method for storing images and is commonly used to store color photos. Fill in the Blank (10 points cach) 13. CPU sizes have been doubling every 18 months, this is known as 14. A 4 bit by 4-bit multiplier circuit would have to have be represented by 4 bits?) output bits. (Hint, what numbers can X Y z (a) P = X Y Z Find the truth table for P in terms of X, Y, and Z.

(20 Points) Write the resulting logic function at points D. E and Q in terms of A, B and C. A B- C E. D E 18. (20 Points) Subtract 6 from 3 (3-6) using 8 bit 2's complement math. Show all work or else you get no credit 19. (20 Points) Multiply 10010 (base 2) by 1101 (base 2). Show all work. 20. (20 Points) We are creating a new 8 bit floating point binary number format. It will consist of a sign bit (O positive, 1 negative), 3 bits for the exponent, and 4 bits for the mantissa. We will be using a 3 offset for the exponent. Assume there is a leading 1 (to the left of the decimal point) for the mantissa. This is the same TINFO 320 format we have been using Convert A2 (hex) to floating point decimal format, show all work
