(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.
The block diagram for a 3-bit ripple counter is shown in Figure (a). Obtain a state table for the number of pulses N = 0 to 8, and draw a state diagram to explain its operation.
