3. ACTIVE LOW PASS FILTER: Find the parameters (R,R,C) of an Inverting Active Low Pass Filter to meet the following criteria. Design an active inverting low pass filter, as shown in Figure 4-5 with a 10 transfer function T(jw) = where f3dB =2 Hz. 1+ jo' @o Note: The value of the feedback resistor, Rfb, should be larger than 1k0. 3 377), in 2 For an input voltage (1) = 0.2 sin(12t+ 7) + 0.2 sin(120t + -), find the 2 corresponding filter output. How does the output compare to the input? INVERTING ACTIVE LOW PASS FILTER Vin Rfb ww Vout Figure 4-5: Inverting Active Low Pass Filter
