What is a composite transfer function?

[Ian_Brooks]

Homework Statement

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).

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.
