We mention the 1st picture. There is a full wave rectifier. . .When the smoothing capacitor discharge, the gap between the Up and Down cycle is filled. . Consequently, the wave-form of the direct current become smooth. . John: OK. . Me: Now, we look at the 2nd picture. . Case 1. high frequency  <--- The curve is very smooth. . The discharge of the smoothing capacitor can easily fill the gap. . Case 2. middle frequency <--- The curve isn't smooth. . The discharge of the smoothing capacitor can hardly fill the gap. . Case 3. low frequency <--- The curve can't continue. . . The direct current is broken. . The discharge of the smoothing capacitor can't fill the gap. .

John: Look at the picture above. Do you see a frequency mixer? This mixer mix the frequency of the output of the modulator and the clock line of RJ45. Me: OK. John: Originally, the modulator output 3-2-1-4, and then, input them to a - b - c - d. Because, the parallel in out line is the branch of the clock line of RJ45. If the clock line of RJ 45 is hacked by hackers. Hackers can change 3-2-1-4 into 0-4-0-4. Consequently, the input to a - b - c - d is 0 , 4, 0, 4. . Me: Take a look at this article .

Me: You may consult it . . https://wodewangzhishime.blogspot.com/2023/12/blog-post_2.html .  Inverter is to delay the flow of current.  Normally, we put a pair of inverter. . In a single Up cylce, I input 3-2-1-4, indeed, only "3" can be input. . Why ?? Because, only "3" comply with the combination of NPN-PNP. . If you put too many inverters, the consequency is that not only "3" comply with the combination of NPN-PNP, but, "2" also comply with the combination of NPN-PNP. . Consequently, stack overflow occur.

Because, it is a latch. . The output depends on the feedback. . If I wanna a 3-1-4-2-4-1-3, what should I do?? You should 3-(down cycle)1-(down cycle)4-(down cycle)2-(down cycle)4-(down cycle)1-(down cycle)3 . 2) The second picture is a modulator. . If I input 3-1-4-2-4-1-3, the output is 3-1-4-2-4-1-3. . Why ?? Because, the output is independent from the feeback. . 3) The third pictue is clear. . . . If there is a feedback, it is a latch. . If there is no feedback, it is a modulator.
