High frequency harmonics of blister equipment

Since the intensity of the harmonic is much lower than the fundamental wave, but the frequency bandwidth and higher harmonic components are very complex, the author believes that it is possible for the images of many (or even all) channels of the TV set within 10m from the high-frequency machine after on-the-spot observation. It interferes with the accompanying sound; for a TV set with a long distance, it may interfere with the sound of a few TV channels in different degrees, and it is difficult to predict which channels will be interfered with.
