Use decoder(s) (74155) with additional gates of your choice and realize the functions below on PROTEUS. F1(X,Y)= (0) F2(X,Y)= (1,2,3) F3(X,Y,Z) = {(1,3,5) F4(X,Y,Z) = {(2,6) Hint: You need to use 74155 in 2x4 and 3x8 configurations. 3-LINE TO-8-LINE DECODER OR 1-LINE-TO-8-LINE DEMULTIPLEXER FUNCTION TABLES 2-LINE TO 4-LINE DECODER OR 1-LINE-TO-4-LINE DEMULTIPLEXER OUTPUTS OUTPUTS INPUTS STROBE 16 DATA 1C 1YO 141 142 1Y3 (0) (1) (2) (3) (4) (5) (6) (7) SELECT B A L L L H X H H H H H H H L L H H H L H H H L L H L H H H 2Y0 241 2Y2 2Y3 1YO 141 142 143 H H H H H H H L H H H H H H H H H H H H H H L H H H H H H H H L H H H H H L H H INPUTS STROBE SELECT OR DATA ct BA x x x H L LL L L LH L LHL L L HLL L HLH L HHL L HHH L H H L H L H H OUTPUTS H H H H L H H INPUTS STROBE 2G H H DATA 2YO 241 2Y2 273 H H H H H L H 2C H H H H H H H H H .
