Adams (1882-1960) HW 9 D UE F RIDAY F EBRUARY 26 33 The circuit of the figure below is the Sallen and Key low-pass filter, which can be used to eliminate unwanted high-frequency noise. (a) Show that the transfer function is H s ( 29 = V out V in = K R 1 R 2 C 1 C 2 s 2 + 1 R 1 C 1 + 1 R 2 C 1 + 1 - K R 2 C 2 s + 1 R 1 R 2 C 1 C 2 where K = 1+R B /R A . Hint: you will need to write three node equations at the indicated nodes. (b) Now let C 1 = C 2 = 1 F, R 1 = R 2 = R A = 1 and R B = 0.8 . These values represent a normalized design. Use MATLAB or equivalent to plot the magnitude and phase responses for 0 ϖ 5 rad/sec. (c) The normalized frequency point at which the normalized gain of the magnitude frequency response of part (b) is 1 2 is to be scaled to a point equivalent to 600 Hz. (i)
