Question: A Bessel-Thomson approximation function is to be flat within 5% of its delay at dc of ms up to the frequency 1800 rad/s.
(a) Determine the appropriate Bessel-Thomson function.
(b) What is the attenuation of the function at 1800 rad/s and at 14,000 md/s?
Design a Bessel-Thomson delay filter having at most a 10%deviation in delay at the normalized frequency ru = 3.0 and at most a l-dB deviation at to = 1.35. The filter is to provide 200-As delay. Complete the design with practical element values and 1-M7411 opamps, and test the performance.
