An implementation of a double delay line canceler with feedback is shown below: x(t) y(t) delay, T delay, T + K K,

(a) What is the transfer function, H(z)?

(b) Plot the frequency response for K = 0 = K2, and K = 0.2, K = 0.5.

9.10. Consider a single delay line canceler. Calculate the clutter attenua- tion and the improvement factor. Assume that = 4Hz and a PRF fr = 450Hz.
