The signals shown in Figure 4-79 are applied to the inputs of the circuit of Figure 4-32.
Question:
The signals shown in Figure 4-79 are applied to the inputs of the circuit of Figure 4-32. Suppose that there is an internal open circuit at Z1-4.
(a) What will a logic probe indicate at Z1-4?
(b) What dc voltage reading would you expect at Z1-4? (Remember that the ICs are TTL.)
