How does an oscilloscope display electrical signals?

How does a cathode ray tube (CRT) display images?
Answer : A Cathode Ray Tube (CRT) display creates images by firing electrons onto a phosphorescent screen, which lights up to form pictures. Here's a simple breakdown of how it works: 1. **Electron Gun** ... lights up, and by controlling which colors are lit and how bright they are, the CRT displays images....

How does a lock-in amplifier extract weak signals from noise?

How does a lock-in amplifier extract weak signals from noise?
Answer : A lock-in amplifier is a powerful tool used to extract weak signals buried in noise by focusing on a specific frequency of the signal. It works based on a technique called *phase-sensitive ... signals are weak and mixed with noise, such as in optical, electrical, or even audio measurements....
