Hi, I suggest that you do the transformation so all the voltage sources and current sources can be unite into one. This is just a suggestion.Please correct me if I'm wrong. Thank you!

Hi, the circuit drawn is known as brigde circuit. I'm not sure whether your working is wrong or correct. But I try to solve this question by the method below. It will be simpler. The V5 is 1.25v with I= 52.08mA. First, i knew that V5= R3(15)/(R3+R1)-R4(15)/(18+6)...

Your answer is the answer for question i. This is because when we refer to the second shift theorem in laplace transform, we can see that the value of 'd' must be the same. In this question, d = 1. Then from there, we can do the laplace transform. For the question ii, I myself not very sure...

Sorry to say that I don understand at all what's going on at the moment. I'm thinking of using multiplication before, but the requirements for it really make me confuse. Besides that, if squaring a number is trivial, then can I assume that y=z? If not, what should I do? What are $1000...

Hi, sorry to say that I didn't understand your question. First, what is 8R? Is it a 8ohms resistor? What is your 3A? Is it a 3 amperes current flow? Maybe if u can attach a more clearer circuit diagram, I might be able to help you. We use superposition when we interfere several sources in the...

Thank for your introduction! I will try my best!

The questios listed all are the theoretical question. We do not have to design the real circuit. For the first question, I already have the answers. But pls help me for the 2nd question.

Hi, hope u solved all the questions already. It's quite an easy questions set.

It's a mix where we need to study the archictecture, all the basic stuffs and at last programming. At the end of this course, we need to design a MC68000-based system. During the exam time, I can't answer the questions. I found out what I learned in class didn't help me a lot. This is because I...

One of my major subjects in this semester is Microprocessor, MC68000. I have a hard time with this subject. Please help me to answer certain questions: 1）Design address decoder for following devices - RAM(128Kbyte) with initial address of $400000 -ROM(32kbyte) with initial address of...

I saw your saying that you are taking microprocessor recently. I had a hard time to struggle with this subject. Are you studying in MC68000? One of my major subjects is microprocessor for this semester. Any tips that I can have to score in this subject? It's so hard for me.
