a telephone engineer feeds a sound signal into the mouthpiece of a telephone.As part of the tests he is making he incresesthe frequency of the sound.HOW WILL THIS EFFECT TYE ELECTICAL SIGNAL PASSING ALONG THE TELEPHONE WIRE?

  • physics -

    It depends. If it is an analoge signal, the frequency. But if it is digital, as on a multiplexed wire, or fiber optics, there will be no difference on the transmitted signal along the "wire".
