Hi I am posting only 4 questions from the whole questions on the pdf file. I need you to work on only Q3,Q4, Q6 and Q7.
Please do not use chat gpt to generate the answer, I’ve already done and it is not correct answer. If you are an expert on ECE then you should be able to solve this question.
Please provide me the answers with the explanation so I can understand. For the answer format, I prefer handwriting. And This is a time sensitive question, so please make sure to meet the deadline.
If you have any question, please let me know. Thank you in advance!
