Question: In Section 8.2 we described a technique for estimating the gain, delay, and the SNR at a point in a system given a reference signal.

In Section 8.2 we described a technique for estimating the gain, delay, and the SNR at a point in a system given a reference signal. What is the main source of error in applying this technique? How can this error source be reduced, and what is the associated cost? Develop a test signal and sampling strategy that demonstrates this error.
