Today is our last workshop for ESE in this semester and we has lectured by Dr. Kamal. Dr. Kamal show us a slide show about our next semester's one subject which is Analog and Diginal Signal. Digital Signal is contributed by binary number. It can store the information of analog signal into binary number then make the analog signal can be transfered far away. Then some electronic device convert the binary number information of the digital signal into analog signal again make other people can get the information wherever the person is.
Go back to the slide showed by Dr.Kamal, the slide has a video i think is get from YouTude make us more easily to understand. The video had said that the digital signal is based on logic level. It is represented by the voltage ranges representib '0' and '1'. 1 is represent the circuit is close and 0 is represent the circuit is open. 1 and 0 can represent all the information since binary number can be any length. More information will need more longer binary number to store it.
Then, Dr.Kamal assign 2 paper to each of us. The first paper is binary number exercise. For this exercise, I can do the addition and subtraction of binary number by just add and minus the 2 binary numbers to a binary number without define the upper and below binary number into decimal number first to find the answer in decimal number. I found the method to do in this binary numbers exercise.
The second paper is communication code worksheet. Finally, we can solve the problem by leading og Dr. Kamal. Then, we are finished our first semester ESE subject. I write the self evaluation form in high mark because I feel that I have learned so much of skills in this subhect. Thank you.^^
