PAL-S

PAL-S is the system of television receiver sets in the early days of PAL system. Here PAL stands for Phase alternating at line rate and S stands for simple. PAL-S is the system of television receiver sets in the early days of PAL system. Here PAL stands for Phase alternating at line rate and S stands for simple. The color hue modulates the phase of a subcarrier named color carrier. In PAL system the polarity of the phase in each frame is reversed to neutralize the undesirable phase shifts introduced during transmission. Thus the effect of undesirable phase shift is positive in one frame and negative in the second frame. Averaging the two, the effect of the undesirable phase shifts in two consecutive frames cancel each other.
