Question:

Do Problem 3-21 by using logic simulation to find the output waveforms of the circuit or a partial truth-table listing, rather than finding Boolean functions.

Problem 3-21

The logic diagram for a 74HC138 MSI CMOS circuit is given in Figure 3-56. Find the Boolean function for each of the outputs. Describe the circuit function carefully.
