Question

1. a. Build a second order low pass filter with -3dB frequency at 5kHz. Given L = 33mH determine C. b. For a step change in the input voltage the output should have minimum settling time with no overshoot. Determine the value of R to satisfy this requirement. c. For the circuit above if only increases what would happen to each of the following responses? 1. final height in response to a step input_ 2. ringing in the output 3. overshoot

Answer 1

1 @ Second order low pass filter with - 3db frequency at SKHZ = to L=33MH CE2 given for 5kHz RL Wort LC VLC and rider LPF 211X5X102= ! - 30.7030F (211X5X103R2X33X103 C = 30.403X10 9 or 3040F 6 min Settling time with no over shoot. then System in a coutically damped system then Duterminant is zowa CEED Characteristic Eq. cis StR s t 1 = 0 betac=0 (B)² - 4x 1 = 0 23 33x103 R=215 = 2*130:4X109 R=2073.502 or 2.073kR]

① If as is increases then final hight in Response to a Step rumput decreases (fidst peak) ie % of peak over shoot is reduced. even we can suppress peak Quer shoot to Zedo at Ego1 Ccritically damped System) ③ Ringing in the coutputs from the above fig. we can observe that Kinging cin the output Corallations or variations are Deduced. It reaches steady sebate quickly ③ Quer shoot Quer shook g reduced. even It can be a "o in magnitude (0%)
