6. a. Apply the input waveforms of the following figure to an XOR gate, and draw the output waveform. b. Repeat with Cheld permanently LOW. C. Repeat with Cheld HIGH. NOTE: Must draw the inputs and align the output with the inputs. - 7. Write the Boolean expression for output X in the figure below. Simplify using De Morgans theorem. Determine the value of x for all possible input conditions and list the values in a truth table. NOR NOR NAND
