What is a composite transfer function?

  1. Oct 17, 2008 #1
    1. The problem statement, all variables and given/known data

    Let F(z) = a0 + a1z-1 + a2z-2 denote the composite transfer function of the transmitter, channel and the matched filter in this ultra wide band system. Find a two tap digital equalizer Heq(z) = w0 + w1z-1 that approximates an IIR zero-forcing equalizer for F(z).

    2. Relevant equations

    3. The attempt at a solution

    I just want to know what a composite transfer function is - i'll try the problem myself.

    I would suppose that the 3 elements of the system you mentioned, namely the transmitter, the channel and the matched filter each have a transfer function of their own. The composite transfer function would be the overall transfer function of all three operating together.
