Unformatted text preview: second ﬁlters: V 2 ≈ E r ‡ 1 + 1 ( ωR 1 C 1 ) 2 · (1 + ( ωR 2 C 2 ) 2 ) Here you have to ﬁnd the exact formula. After you do this, plot the approximate and the exact expressions for V 2 ( ω ) /E for the following parameter sets (a) R 1 = 10, C 1 = 10, R 2 = 1, C 2 = 1 and (b) R 1 = 10, C 1 = 10, R 2 = 0 . 1, C 2 = 10 Note that the products R 1 C 1 and R 2 C 2 that determine the characteristic frequencies of the ﬁlters are the same in both cases. 1...
