Please list steps. I will rate, thank you.

Exercise 3: The input line of a demultiplexer (decoder is kept high (+5 Volts). There are two address lines denoted by the logic variables A and B (A is the lowest order bit) capable to address 4 output lines from line 0 (input 00) to line 3 (input 11). At the output of the decoder there are 4 OR gates each having 4 input lines. Initially these input lines to the OR gates) are not connected anywhere (input is then considered 0. The outputs of the OR gates are denoted with the logic variables W, X, Y and Z. Indicate how Input these input lines (to the OR gates) should be connected to the decoder output lines in order for the following logic function to be implemented. The input to the logic function is the A and B logic Output variables and the output the W, X, Y and Z logic variables. Connection between two lines is indicated with a dark circle (or square). Open connection 10 0 (unconnected lines) is indicated with a white (transparent) circle. Each input line to the OR gates can be connected only to one demultiplexer output. 0 2 3 B A
