(a) Design a passive high pass filter that has a maximally flat response with a 50 Ω resistive load. Assume that the cut-off frequency is 40 kHz and that at a frequency of 25 kHz, the response is down at -10 dB.
(i) Determine what type and order of filter is best suited for this application.
(ii) State the filter transfer function.
(iii) Sketch the expected (approximate) frequency response of the filter
(b) Draw the filter circuit diagram showing the component values and determine the actual attenuation obtained at f=25 kHz and at f=40 kHz.
(c) By simulating the circuit or otherwise, obtain the actual frequency response of the filter.

Q. The energy stored in a 2-µF capacitor is given by w c (t) = 9e -2t µJ for t ≥ 0. Find the capacitor voltage and current at t = 1s.
If a current is passed through a coil, it creates a flux within the coil. Any attempt to change this flux will create a back emf that acts to oppose the change. Consider again
