We have a single pole RC lowpass filter (series R shunt C) which has (Vo/Vin)jw = H(jw) = w₀/(jw+w₀).

You measured the frequency response of this circuit in lab.

Now use the formula we derived in class to calculate the attenuation in dB for the following frequencies:

w = .01w₀, w = .1w_0, w = w_0, w = 2w_0, w = 10w_0, w = 20w_0, w = 100w₀

Hint: Attenuation (dB) = 10log|H(jw)|²

Compare attenuations for frequencies 10w₀ and 20w₀ to find the dB per octave attenuation slope.

Compare attenuations for frequencies 10w₀ and 100w₀ to find dB per decade attenuation slope..
