What is the primary function of the 3-state buffer shown in figure 7.5?
- To provide output that is the inverse of the input when the enable signal is low
- To provide output that is always low when the enable signal is low
- To provide output that is always high when the enable signal is low

What is the relationship between the number of inputs (n) and the number of output bits (m) in the encoder shown in figure 7.7?
What is the relationship between the number of inputs (n) and the number of output bits (m) in the encoder shown in figure 7.7?
- n = 2^m (correct)
- n = m + 1
- n = 2m
- n = m^2
