Question: A fundamental-mode circuit with two inputs (x, and x2) and one output, z, is required. Whenever x, is 0, z is 0. The output z goes to 1 on the first 0-to-1 transition of x2 when x, is 1. The output remains at 1 until x, returns to 0. No change in output occurs for any other conditions.
(a) Draw a primitive flow table and reduce it.
(b) Specify all the outputs in the reduced flow table.
(c) Find a race-free state assignment.
(d) Derive the circuit diagram using delay lines.
(e) Derive a circuit diagram using unclocked SR flip-flops.
