Question
A synchronous state machine
has two inputs (X1 and X2) and
two outputs (Z1 and Z2). The
inputs represent a 2-bit binary
number (N). If the present value
of (N) plus the previous value of
(N) is greater than (2), then
(Z1=1). If the present value of (N)
times the previous value of (N)
is greater than (2), then (Z2=1).
Otherwise, (Z1Z2=00). When
the first pair of inputs is
received, use (0) as the
previous value of (N). The circuit
of the aforementioned state
machine includes
AND-
.gates
