A circuit has four inputs D, C, B, A encoded in 8421 natural binary form. The inputs in the range 0000 to 1011 represent the months of the year from January (0) to December (11). Inputs in the range 1100 to 1111 (i.e., 12 to 15) cannot occur. The output of the circuit is a logical 1 if the month represented by the input has 31 days. Otherwise the output is false. The output for inputs in the range 1100 to 1111 is undefined. Draw a truth table to represent the problem and use it to construct a Karnaugh map. Use the Karnaugh map to obtain a simplified expression for the function.

An engineer and her son share an older model car, but the son keeps either leaving the keys in theignition or leaving the lights on and draining the battery. She decides to design a logic circuit that willprevent him from doing either of those.She adds 3 sensors to the car that will send either a logic 0 or a 1 to the logic circuit. One sensor isadded to the seat (S) with S=0 indicating that there is no one in the seat (no driver in the car) and S=1meaning that there is a person in the driver’s seat. The second sensor is added to the ignition (K) withK=0 indicating that the key is not in the ignition and K=1 indicating that the key is in the ignition. Thethird is added to the lights (L) with L=0 indicating that the lights are turned off and L=1 indicating thatthe lights are on. The output of the circuit is a signal that goes to a buzzer (B) where B=1 means that thebuzzer is on to remind the son to check the ignition and/or lights. B=0 indicates that the buzzer is off.

A seven-segment display is a device composed of 7 elements, as shown in the figure below. Each element is selectively lit to form patterns such as numbers or letters. For example, to display '0', the segments A, B, C, D, E and F have to be simultaneously lit. A circuit decoder takes in a 4-bit binary number and produces the outputs A, B, C, D, E, F and G. The outputs of the decoder are then fed to the seven-segment display as shown in the figure. The seven-segment display should show the sum of the 4-bit input + 1. For example, if the 4-bit input is 000 , the decoder’s output will lit up the seven-segment display that will show the numerical number 1. This corresponds to the decoder output of 01100002. In the case wherein the 4-bit input = 1001 , the decoder’s output will lit up the seven-segment display that will show the numerical number 0. This corresponds to the decoder output of 1111110 . The decoder’s output line should be logic “1” if the segment will be lit and “0” otherwise.…

. Design a logic circuit that controls an elevator door in a three-story building. The circuithas four inputs. M is a logic signal that indicates when an elevator is moving (M=1) or stopped (M=0).F1, F2 and F3 are floor indicator signals that are normally LOW, and they go HIGH only when theelevator is positioned at the level of that particular floor. For example, when the elevator is lined uplevel with the second floor, F2=1 and F1=F3=0. The circuit output is the OPEN signal which isnormally LOW and is to go HIGH when the elevator door is to be opened.
