High-Pass Filters: SAQ Solutions

Listed below are the solutions to the SAQs on high-pass filters:

1. No, it is not best to use a cutoff frequency of 61 Hz.
   A higher cutoff frequency is preferred if possible because frequencies will start to be attenuated gradually before the cutoff frequency. The cutoff frequency does not line up with where attenuation begins in a real filter.
2. A. A capacitor then a resistor in the following orientation: (Tinkercad used for circuit diagram).
   For a high pass filter, want the letter higher up in the alphabet (C comes before R) to be closer to the positive terminal of the circuit.
3. The cutoff frequency is 4.83 kHz.
   Use the cutoff frequency formula: fc = 1/(2*pi*R*C) (or 4830 Hz)
4. Increase the order of the filter by cascading it with an identical high-pass filter to your first order filter in series.
   Cascading filters with the same cutoff frequencies will make the drop off in frequency occur more rapidly.
