Question

an asynchronous circuit is described by the following excitation and output functions:

$Y = x _1x _2’ + (x _1 + x  _2’)y$

$z = y$

1. Draw the logic diagram of the circuit.
2. Derive the transition table and the output map.
3. obtain a two-state flow table.
4. Describe in the words the behavior of the circuit.
