Noise generated in the DVD player is radiated from the audio and video
signal cables. In addition, although the player body is shielded with a
metal case, radiated noise is emitted from the connector port openings.
A DVD player processes image signals using the MPEG2 method. Since
image processing requires high-speed signal processing, signals are
transmitted at a very high speed. Therefore, high-frequency noise
around 1GHz, may be radiated. |
