Finding bandwidth

  1. Mar 31, 2017 #1
    • New user has been reminded to post schoolwork in the Homework Help forums and fill out the HH Templatge showing their work
    The commercial AM radio channels are separated by 10 kHz. What is the maximum bandwidth of the base-band signal each of these channels can carry?

    It is half the bandwidth, 5 kHz.
    AM transmission requires two sidebands, one each side of the carrier, and each has the same width as the baseband.

    There is an interesting discussion on this subject in an ITU Recommendation at the following URL:-
    Notice that in Europe a 9kHz channel spacing is used with 4.5kHz audio restriction.
