摘要: When the second channel in a picture-in-picture (PIP) receiver is turned off by user, it automatically tuned to station selected for first channel. Both channels thus process signal having same picture information. After partial processing, two signals are averaged, creating which has components but substantially reduced noise components. This then subjected remaining standard processing and applied tube.
