A transversal equalizer with K taps has an impulse response
where T is the delay between adjacent taps, and a transfer function
The discrete Fourier transform (DFT) of the equalizer coefficients {ck} is defined as
a. Show that bk = ck, by substituting for En in the above expression.
b. From the relations given above, derive an equivalent filter structure having the z transform
c. If E(z) is considered as two separate filters E1(z) and E2(z) in cascade, sketch a block diagram for each of the filters, using z−1 to denote a unit of delay.
d. In the transversal equalizer, the adjustable parameters are the equalizer coefficients{ck}. What are the adjustable parameters of the equivalent equalizer in (b), and how are they related to {ck}?
