The lock is open when ABC corresponds to 110 and 010. For all other codes, the lock is closed. 1) Construct the truth table for the lock operation. ii) Write the logic function. iii) Implement using basic gates. [2] [2] [1] 18 A multiplexer circuit has 4 selection lines to control 16 inputs. The logic function is given as F(A,B,C,D)-m(0,1,4,5,6,9,10,12,14,15) i) Implement the function using 16xI MUX ii) Implement the function using 8x1 MUX by keeping A as the input variable.
