What is vsb crt?

VSB CRT stands for Vestigial Sideband Cathode Ray Tube. It is a type of cathode ray tube used in analog television broadcasting to display video signals. The VSB CRT was developed as a solution to the problem of bandwidth limitation in analog TV broadcasting. It uses a vestigial sideband modulation technique that allows more efficient use of the available bandwidth.

The VSB CRT displays the video signal by scanning an electron beam across the face of the tube. The signal is then modulated onto a carrier wave and transmitted via an antenna. At the receiving end, the signal is demodulated and the video is displayed on the VSB CRT.

The VSB CRT technology was most commonly used in North America for over-the-air television broadcasting between the early 1990s and the early 2000s. It has since been replaced by digital television broadcasting technology, which offers higher picture quality and more efficient use of bandwidth.
