One way to specify a combinational circuit is to describe its function by a truth table, in which we list all possible input combinations and their desired output values. Assume that the circuit has n inputs.
(a) What is the size (number of the rows) of the table? (b) What is the problem with this approach?

8. For this problem, you are to design a simple combinational logic circuit and then use Logisim to simulate and test the circuit. The circuit is a 2- bit priority encoder with inputs X2 and X1 and outputs Y1 and Yo. The circuit behaves as follows: oIf X2X1 00, then Y1Yo 00 (no active input) If X2X1 01, then Y1Yo = 01 (low-priority input, X1, is active) If X2X1 1-, then Y1Y0 10 (high-priority input, X2, is active) Note that...

9. (Expression Truth Table) Determine the truth table for the three-input XOR function y = 11 12 13. You may first evaluate i n and then evaluate y as y=( 12) 13. In the truth table, besides the columns for 11.12.13 and y, also include a column corresponding to I 1. Also use a word statement to describe this logic function and indicate a possible application of the function 10. (Expression Circuit) Draw a circuit schematic which realizes the logic...
