G Assume all the impedances except 5 are resistors, and that 5 is a capacitor. Assume 1 = 1, 2 = 2, 3 = 3, 4 = 4 and 5 = 1 . Derive the frequency response with 1, 2, 3, 4 and . Then using 1 = 2 = 2.4 kΩ, = 0.01 μF,3 = 100 kΩ, 4 = 50 kΩ, draw the gain of the filter from 20 Hz to 20kHz and prove that the filter is a low-pass filter. After that, switch 3 and 4 and draw the gain from 20 Hz to 20 kHz and prove that the filter is a high-pass filter
