(b) Mr. jojo, lives in a four-flat house, the conditions of the lighting system wa very bad and he needs help. He wants the design to be as follows, a combinational circuit that controls the ceiling lights in my downstairs hallway, which has three wall switches: one at the front door (A), one at the back door (B) and one in the family room (C). When I walk in the front door, the ceiling lights are off, the A switch is ON and both the B and C switches are OFF, From these initial conditions, changing the position of any switch should turn the lights on; changing the position of any switch (again) should turn the lights off,

2. Design a logic circuit with two inputs and 4 outputs, with each of the outputs hooked up to an LED. Only the first LED should light up when the input values are 00. Only the next LED should light up with the input values are 01. Only the following LED should light up for 10, and only the last LED should light up for input 11. Thus for each input combination, you should have one LED only being lit. This is called a DECODER circuit, you are decoding 2 bit binary input to one of 4 discrete outputs. a. Create the truth table (use the standard truth table format). b. Write a Boolean expression that corresponds to the truth table.

Course: Digital Logic Design You have to solve the question step by step and clearly Please. You have to solve in a 1 hour. Question is well explained you have to read first carefully then answers properly in a single solution: Question 5: Colors of different nature can be produced by mixing three fundamental colors that are red, green and blue. Consider you are assigned a task to design a digital system that is equipped with three different LEDs and four different color sensors. One LED is red (symbolized with R), one is green (symbolized with G) and one is blue (symbolized with L) while one sensor detects white color (symbolized with W), one detects black color (symbolized with B), one detects cyan color (symbolized with C) and one sensor detects magenta color (symbolized with M). It is known that each color sensor produces logic 1 output if and only if when an object of its corresponding color passes in front of it, otherwise logic 0. Each LED turns on when logic 0 is provided to…
