Butterworth Filter Problem

Please give clear steps ! Thanks a lot in advance :)

The specs of a 3rd order HP filter are: (omega p, Amax) = (2 pi * 5000.2 dB), (omega s, Amin) = (2 pi * 1250.30 dB), omega p > omega S. A 3rd order Butterworth 3dBNLP prototype circuit is given below and has transfer function Compute L in H and C1 and C2 in F to realize the 3 dB normalized 3rd order Butterworth transfer function. Using (a), construct a NLP circuit according to Step 5 of the above HP design algorithm. Using step 6 of the above HP design algorithm, construct the NHP filter circuit. Draw and label the circuit. Now construct the final HP circuit design if the final value of the largest capacitor is to be 10 nF. What is the value of K f to be used in the scaling? What is value of Km ? Draw and clearly label your final circuit.
