Analog Crt Signal

Click For Summary

A CRT TV operates by using a video signal to control an electron gun, which fires electrons onto the screen to create images. The deflection coils move the electron beam horizontally and vertically, while the video signal determines the specific pixels that are illuminated. Synchronization of the electron gun firing and beam deflection is achieved through a combination of local and common oscillators, ensuring accurate image display. The CRT's electron gun functions similarly to an audio amplifier's grid, with nonlinearity affecting brightness levels. Modern digital signals improve picture quality by enhancing the data content compared to traditional analog signals.

No @sophiecentaur I am not engineering anything with this , I am doing other things at the moment this is just reading and understanding.

I'm not sure how to treat this. On one hand, everyone should be free to fantasize. On the other hand, PF is not fond of giving advice how to do something that would be illegal. Even if you don't plan anything illegal, potentially thousands of other people in the coming years may find this thread by Google search and some of them may use the information for their own purposes.

You have adequate answers to your original question. Thread closed.
