Farnsworth's principles

Farnsworth's principles relate to how a television image is created and displayed. He emphasized that the image should be formed line by line with precise timing and synchronization, ensuring smooth motion and clear details. His approach involved scanning images quickly across a screen using electrical signals, which allowed for stable and high-quality pictures. The key ideas include raster scanning (moving sequentially across the screen), synchronization signals to keep the image steady, and maintaining consistent brightness and contrast. These principles laid the foundation for modern television technology, enabling broadcasts to be clearer and more reliable.
