From Information Theory Aspect

  • Our world consists of information.
  • What is information? Their measurement, value.
  • Information transferring model.
  • How to maximum the usage of a communication channel.

What’s the value of information

  • 烽火连三月 家书抵万金
  • Simple, the probability of being alive is very very small, uncertain, and when it happen/we know s/he is alive, this information values.

What is ECE?

    • The invention of telegram helped people to send messages remotely
    • The Morse Code make it happen to represent information using 0s and 1s
    • For chinese, 中文電碼，又稱中文商用電碼、

中文電報碼或中文電報明碼

    • 在港澳，每個有中文姓名的市民的身份證上，

均會在他的姓名下面，印有中文電碼

    • 中文電碼 is i.e., telegraph code for
    • Chinese information transmitting.

What is ECE? �

  • Telephone
    • Analog telephone: converts sound, typically and most efficiently the human voice, into electronic signals
    • Digital telephone: the signals in current/wave form are converted into digital 0s and 1s and then converted back
  • Telephone net
    • One to one telephone

AI and Big Data

  • Data collecting end device
    • Like Apple Watch, we need sensors as data collectors
    • We have many other types of sensors, and collect data
    • From sensors, to system, to big data, next? AI predictor?
