I need the answer as soon as possible

3. a) Determine the order, N, and 3-dB cutoff frequency, cc, for a Butterworth lowpass analog filter which will pass frequencies up to 2 kHz with no more than 1 dB of loss and reject frequencies beyond 4 kHz with at least 25 dB of attenuation. b) Plot the poles of the filter in the complex s plane, c) Calculate the Q for all poles. d) In terms of implementing this filter, which of the poles are going to be the most trouble? Why? e) Sketch the circuit for implementing this filter without specifying component values. 3. a) Determine the order, N, and 3-dB cutoff frequency, cc, for a Butterworth lowpass analog filter which will pass frequencies up to 2 kHz with no more than 1 dB of loss and reject frequencies beyond 4 kHz with at least 25 dB of attenuation. b) Plot the poles of the filter in the complex s plane, c) Calculate the Q for all poles. d) In terms of implementing this filter, which of the poles are going to be the most trouble?
