Why is color TV static is black and white?
The same reason fuzz on a stereo receiver is in mono - the extra information for the stereo signal is on a 38 kHz subcarrier, where the color information is on a 3.579 MHz subcarrier - if that signal level is too low, it shuts down the color (for compatibility with B&W broadcasts) - it's all a matter of downward compatibility :)
Sorry, I had to answer that one :)
