Unformatted text preview: . Suppose these 7 bits are transmitted over a
noisy channel and Z = z6z5z4z3z2z1z0 is received. Assuming that at most two
bits get altered during transmission, draw a circuit which outputs a 1 precisely
when an error has occurred (i.e., your circuit will output a 1 if Z is incorrect).
8. Design a 4-input, 1-output network N that computes the function f given
f(a,b,c1c0) = a'
a' + b
a+b if c1c0 = 00
if c1c0 = 01
if c1c0 = 10
i f c1 c 0 = 1 1 i.
ii. Give a sum-of-products (SOP) Boolean expression for f.
Draw the circuit corresponding to your expression in part (i). Us...
