Assignment:
A filter has the following characteristics:
Attenuation is 0 dB from 0 Hz to 2.5 kHz. Phase angle decreases linearly with increasing frequency above 2.5 kHz. Above 5 kHz the filter has steadily increasing attenuation.
At 10 kHz attenuation is 6 dB and at 20 kHz attenuation is 24 dB.
a. Is this a low pass, high pass, band pass or band stop filter?
b. What is the attenuation per octave between 10 kHz and 20 kHz?
c. If the filter is known to be a Butterworth filter, what is the value of its order, N?
Provide complete and step by step solution for the question and show calculations and use formulas.
