Pre lab Exercises
 

1.    Redraw the block diagram in FIGURE 1 showing the inputs and outputs to actually represent your comparator circuit.

2.    Derive a truth table describing the operation of the circuit.

3.    Obtain the Boolean Expression for the outputs using minimization techniques.

4.    Implement the circuit on paper (in the log book) using TTL components.

5.    State the numbers of the TTL equivalent IC at each of the gate and assign the appropriate pin numbers for all the inputs and outputs of each gates.

6.    Give the types, number and quantity of chips that will be used to build the circuit in the lab using the format as shown in Appendix B, Table 2.

7.    Doing reverse engineering process, obtain the Boolean Expression (BE) from the circuit that you have obtained in (4) to check whether you have implemented the circuit on paper correctly. If there is any mismatch in the BE, locate the error and make necessary changes in your circuit diagram.
