Review the behavior of the multiplexer and the decoder. Another similar component is the demultiplexer. It should perform the converse operation of the multiplexer: it should pass its single input signal to exactly one (and only one) of the outputs, as determined by the appropriate number of select bits. The remaining outputs should be zero. Your task is to draw a 4-output demultiplexer using logic gates. Use SO (that is S"zero") to identify the least significant select bit, and clearly identify output 0 (zero) on your circuit. Make sure you also clearly identify which wires that cross are connected, by using a dot (just like digital does). (You can assume that the input and each of the outputs are 1-bit).

H.W :- 1) A four logic-signal A,B,C,D are being used to represent a 4-bit binary number with A as the LSB and D as the MSB. The binary inputs are fed to a logic circuit that produces a logic 1 (HIGH) output only when the binary number is greater than 01102-610. Design this circuit. 2) repeat problem 1 for the output will be 0 (LOW) when the binary input is less than 01112-710- Saleem Lateef

Design a combinational circuit using multiplexer for a car chime based on thefollowing system: A car chime or bell will sound if the output of the logic circuit(X) is set to a logic ‘1’. The chime is to be sounded for either of the followingconditions:• if the headlights are left on when the engine is turned off and• if the engine is off and the key is in the ignition when the door is opened.Use the following input names and nomenclature in the design process:• ‘E’ – Engine. ‘1’ if the engine is ON and ‘0’ if the engine is OFF• ‘L’ – Lights. ‘1’ if the lights are ON and ‘0’ if the lights are OFF• ‘K’ – Key. ‘1’ if the key is in the ignition and ‘0’ if the key is not in the ignition• ‘D’ – Door. ‘1’ the door is open and ‘0’ if the door is closed• ‘X’ – Output to Chime. ‘1’ is chime is ON and ‘0’ if chime is OFF

H.W: Reduce the combinational logic circuit in Figure below to a minimum form.
