Are two the truth tables identical? 2.5 Draw the circuit schematic forf= z and then convert the schematic to NAND gates using the steps illustrated in the textbook. 2.6 Evaluate f (x +y(+ z) for x 1,y 0, and z 1 and for x 1,y 1, andz 0. 2.7 Draw the circuit schematic for f (x+ y) (v + z) and then convert the schematic to NOR gates using the steps illustrated in the textbook. CE 2.8 Givenf xy+ yz (an SOP expression) determine its equivalent POS expression. Hint: First find the SOP of 7 and then use the rule "POS expression off Comple- ment of the SOP expression of 7
