"Thermal Noise" is a phenomenon where everything makes EM noise, just from thermal energy.

If you were to put such a TV in a faraday cage, with an RF termination, you would see something similar. Because noise is inherently part of the circuitry and amplifiers.

  2. The entire showerthought must be in the title
  3. Avoid politics
    • 3.1) NEW RULE as of 5 Nov 2024, trying it out
    • 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    • 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct
