ACTIVITIES

Logic Gates (cont’d)

Students should be able to:

5.2. use truth tables to represent Use of logic tutors
the function of logic gates (combinations of logic gate
with no more than two chips on one board) to
inputs; investigate the truth tables
of these gates.

5.3. re-design a logic circuit to Circuit should be reduced to
contain only NOR gates or minimum chip count.
only NAND gates;

5.4. analyse circuits using
combinations of logic gates
to perform control functions;

5.5. construct truth tables for a Students should familiarise Logic tutor can be used to
combination of logic gates; themselves at the earliest investigate these
possible opportunity with combinations.
the application of logic
gates to solve simple real-
world problems and a
familiar practical example
should be described.

5.6. interpret truth tables for a
combination of logic gates;

5.7. use timing diagrams to
represent the response of
digital circuits to different
input signals;

5.8. draw a circuit to show the From two NORs and an AND Set up circuits to investigate
construction of a half-adder; or from EXOR and an AND. both the half adder and full
adder.

5.9. explain the operations of a
half-adder;

5.10. use two half-adders and an
OR to construct a full-adder;
