2. a) Draw a circuit that generates the following truth table: Using the Logisim circuit simulator: 1. Using 2-input AN gates and single-input NOT gates only, draw a 3-to-8 decoder (use the 2 -to-4 decoder in Slide #7in Lecture 3B as a guide). Paste a copy of your Logisim circuit here. Hint 1: This circuit uses S2 and S1 to select one of four possible outputs. You will need to draw a selector and decoder plus the four different logic gates (See Lecture 3B, slides 6,7,8 ) Hint 2: The first four X values belong to one logic gate (which is it?), the second four X values belong to the second logic gate, etc. Hint 3: Note that S2 and S1 may need to be reversed as decoder inputs.
