Obtain a primitive flow table for an asynchronous circuit with two inputs, x1 and x2, and two outputs z1,z2 that operates according to the following specs:
a) when x1x2 = 00, the output z1z2 = 00
b) If x2 changes from 0 to 1 while x1 = 1, the output is z1z2=01
c)When x2=1 and x1 changes from 0 to 1m, the output is z1z2=10
d) Otherwise, the output does not change
