Lab: The objectives of this lab are to simplify a Boolean function, design the simplified logic circuit using a software. 1: problem: You need to obtain: the truth table, the equation that describe the system, simplify the equation using Boolean algebra and K map. (Taken from digital system Tocci and all) Figure shows the intersection of a main highway with a secondary access road. Vehicle-detection sensors are placed along lanes C and D (main road) and lanes A and B (access road). These sensor outputs are LOW (0) when no vehicle is present and HIGH (1) when a vehicle is present. The intersection traffic light is to be controlled according to the following logic: 1. The east-west (E-W) traffic light will be green whenever both lanes C and D are occupied. 2. The E-W light will be green whenever either Cor Dis occupied but lanes A and B are not both occupied. 3. The north-south (N-S) light will be green whenever both lanes A and B are occupied but C and Dare not both occupied. 4. The N-S light will also be green when either A or B is occupied while C and D are both vacant. 5. The E-W light will be green when no vehicles are present. Using the sensor outputs A, B, C, and D as inputs, design a logic circuit to control the traffic light. There should be two outputs, N-S and E-W, that go HIGH when the corresponding light is to be green. Simplify the circuit as much as possible and show all steps. Results: Complete the true table

Lab Report #2 2- Show how do you find the function N/S and E/W, use Karnaugh maps 3-: Using a software draw a schematic diagram for the function obtained. Connect switches for inputs. Connect probes for the inputs and the outputs. Change the switch positions and compare the output of the circuit to the truth table for the function. Build and insert the circuit built the soft and the you need. 4-Remove the switches and connect "Input Signals" for the four inputs. Define the input signals so that the
Build and insert the circuit built in the software and measure the values you need. Lab Report #2 inputs follow a binary sequence, for example 0000, 0001, 0010, 0011, 0100, ...., 1111. Using a timing diagram compare the output obtained in the simulation to the theoretical values in the truth table. Paste the timing diagram obtained. 4- Turn in a report consisting of a title page, goals of the lab, printed schematic of the circuit and printed simulation timing diagram, a comparison of simulated waveform results with the truth table, and a conclusion summarizing what you have learned in this lab. 4
