(a(i))[1]
Draw the symbol that represents a diode.
(a(ii))[1]
Draw the symbol that represents a NOT gate.
(b(i))[2]
Complete the truth table in Table 9.1.
(b(ii))[1]
State another single gate that is equivalent to the section of the circuit between I1 and Z.
(c)[4]
Using two logic gates, design and draw a digital circuit with two inputs and two outputs which matches the truth table shown in Table 9.2. Use either the usual logic gate symbols or correctly labelled square boxes in your diagram.
