--- Quote from: loop123 on April 04, 2024, 07:16:36 am ---But I still can't totally comprehend the above description "You are measuring far below the noise-range of conventional amplifiers."? How so? What is typical noise-range of conventional amplifiers and how could it be measuring far below? Please give actual figure as examples. Thank you. --- End quote --- The noise floor is relevant when you specify frequency bandwidth. You can go below that noise floor if you apply lowpass or bandpass filter to reduce bandwidth, because it gives you processing gain for SNR. This is because noise power is spreaded across the frequency bandwidth. But if noise is not flat and has more complex shape, this is different story... |

You guys know a lot. Let me ask my last question in case one of you can answer this. Are you guys familiar with Parallel Factor Analysis (PARAFAC)? What kind of signal and noise floor where PARAFAC needs to be used? In the g.USBamp experiments. 7 channels were used. Then Parallel Factor Analysis were used in the 7 channel data. When the second factor was done, the signals came out clearly. What is the meaning of the first and second factor in Parafac? The signal is not exactly out of this world. The idea is akin to symmetry breaking in the Big Bang. In the very hot soup in the Big Bang. There is more symmetry and electroweak is one force. When the universe cooled down. The force separates. But we can recreate at least partially the condition of the hot soup via the Large Hadron Collider for example. Likewise. Unconventionally. There is something akin to symmetry breaking in the cool universe. The idea is that at default mode. The vacuum is in certain state. But by initiating phase transition or symmetry breaking, the laws of physics can change and biopotentials of this force can be measured (the most outward manifestation of it). So many scientists have done these experiments like the scientist Dr Tiller. In other words, you need to change the properties of the vacuum to make the signal appear in your body. And there are people in this world with the ability to change the vacuum state with their mind. Yes. Shades of X-men. I happened to meet a hundred of them in my lifetime. Unfortunately, James Randi is dead or we could beat him. Well. What I describe is just so unconventional for discussions in EEVblogs and others where people minds are only focus on this conventional world. This is the exact reason why most ignore all these studies and results. Because in their extremely materialistic viewpoint, only bolt and nut and gross materialism exists. And all these I described are just pure nuts. I'm saying this because the signal is not exactly out of this world. Only out of ordinary vacuum state as per Dr. Tiller description but can be manifested in this world and read by ordinary instruments. He had many experiments and positive results that most completely ignored. If I see positive signal, and no one believes it. It is ok as it is for my own knowledge. Anyway. Just tell me what is the second factor in Parafac for my last question and the use of Parafac in noise floor and signal analysis you have heard about. Thank you for all the helpful tips. I learnt so much all these months. |

May I suggest that you don't explore PARAFAC for the time being. In the hands of unexperienced users, it is a great tool to extract signals and patterns where there are none (of significance). Come to think of it -- while the similarity of names is a coincidence, PARAFAC may indeed be perfect for exploring para-psychology and paranormal phenomena. ::) |
