Unformatted text preview: ( t ). (c) Deﬁne the frequency response of the system as H ( ω ) = Y / X . Compute the magnitude | H ( ω ) | and the phase ∠ H ( ω ) for ω = a 1 / 10 , a 1 / √ 3 , a 1 , √ 3 a 1 , 10 a 1 . Sketch and label the magnitude and the phase of the frequency response for a 1 / 10 ≤ ω ≤ 10 a 1 . Is this a lowpass or a highpass ﬁlter? c ± 2001–2007, P. Mathys. Last revised: 12-06-07, PM. 1...
