PAL (Phase Alternating Line)

PAL (Phase Alternating Line) is a color TV broadcasting system developed in the 1960s, primarily used in Europe and some other regions. It transmits color images by encoding color information through phase variations, which helps reduce errors caused by signal interference. PAL alternates the phase of the color signal with each line, effectively canceling out color distortions over multiple lines, resulting in more stable and accurate color reproduction. It operates alongside black-and-white signals, ensuring compatibility. Overall, PAL provides reliable, high-quality color television broadcasts by improving color stability and consistency during transmission.
