Equipment 1 DC Power Supply 2 Diodes 1 1 k resistor 1 7408 IC 1 7432 IC Preliminary Work 1) Draw the logic diagram to implement the following functions using AND and OR gates. Form a truth table for each and show the output state for each possible input combinations (notice that there are 16 possible input combinations). a) Y = AB + CD b) Y = (A+ B)(C + D) c) Y = A(BC + D) EEN 204 Laboratory 2 EXPERIMENT 8
Experimental Procedure I. Diode AND Gate : Set up the circuit shown in Fig. 8.1. Collect data with the D.V.M. and complete Table 8.1. Figure 8.1 Simple AND gate. Table 8.1 II. Diode OR Gate : Set up the circuit shown in Fig. 8.2. Collect data with the D.V.M. and complete Table 8.2.
