## Question:

A sequential circuit is shown in Figure 4-49. The timing parameters for the gates and lip- lops are as follows:

**Figure 4-49:**

**(a) **Find the longest path delay from an external circuit input passing through gates only to an external circuit output.

**b) **Find the longest path delay in the circuit from an external input to positive clock edge.

**(c) **Find the longest path delay from positive clock edge to output.

**(d) **Find the longest path delay from positive clock edge to positive clock edge.

**(e) **Determine the maximum frequency of operation of the circuit in megahertz (MHz).
