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.
