Life is a book of communication principles! Do you understand?

The meaning of life lies in being in a cyclical random process, that is, in the trajectory of your life, there are always ups and downs and good and bad situations, and you never know what will happen next; the pain of life is that, looking back on the years, your random process is nothing more than a cyclical and stable random process. No matter how you change, you can never escape the Five Finger Mountain of Fate, because Tongyuan Book tells us that this process has the ergodic nature of various states - what you experience is nothing more than the repetition of various tragedies.

The relationship between ordinary people and public figures is like an amplitude modulated signal. The existence of countless people fulfills the value of a few people - you are just an insignificant point in the large frequency component of the carrier, and those dazzling public figures are the so-called envelope of the signal, allowing you to see it clearly enough.

The relationship between people is like the HDB3 code. It cannot be too intimate, so we introduce a zero value between us; it cannot be too unfamiliar. If the distance exceeds three zero points, I will find ways to get you back.

The relationship between you and me is like the relationship between an input signal and a matched filter - my love for you only reaches its peak when your affection for me disappears.

The sinc function tells us that even if you and he are standing opposite each other, as long as your hearts are continuous, even at the zero point where there is no DC component, your power spectra can still be closely connected.

Life is a Fourier series. The harder it is to do something, the greater its frequency value and the smaller its amplitude. Don't worry too much, because we should realize that limited life cannot depict infinite Fourier series. Infinite imagination and dreams are just dreams after all, because their amplitude is too low. It is better to be down-to-earth and do everything within your ability.

The Nyquist theorem tells us that if your life is below the Nyquist rate, then as long as you invest a certain amount of time and energy to design the filter, you will not be disturbed by others. Remember, don't be too tired, what can be achieved will eventually appear; walk slowly so that you can see the scenery on the road clearly and not be lost by interference.

How many of our ideals and promises have been completely changed or even destroyed after a few modulation tests? Is there someone who can use the appropriate demodulation method to show my light to everyone?

Cups and washbasins are like two brothers in distress in the frequency band signal. After multiplying by the complex carrier, it is found that the two actually come from the same source.
