Credit Weight: 0.5 Description: General techniques for controlling the positions of poles and zeros by means of feed forward and feedback amplifiers. The complex critical frequencies produced by different amplifier configurations are then applied to obtain realizations of second order low-pass, high-pass, band-pass, band-stop and all-pass functions. RC oscillators are treated as second-order realizations with imaginary axis poles. Butterworth, Chebyshev and Bessel approximations. Offering: 3-1.5; or 3-1.5
