Unformatted text preview: ) = (T L )*ln(2)] Frequency response cutoff frequency Solve : [SEE PAGE 7 IN EXPERIMENT 5 NOTES] Definition : In a filter, the cutoff frequency is the point where the response is 3 dB down in amplitude from the level of the passband. Beyond the cutoff frequency, the filter will attenuate all other frequencies, depending on the design of the filter. Frequency response quality factor (only used for bandpass) Solve : Q = f o / (f 2 f 1 ) Definition : A measure of the sharpness of resonance or frequency selectivity of a resonant vibratory system having a single degree of freedom, either mechanical or electrical. For plotting on logarithmic paper, use: 20 log 10 |H(jw)| (result in dB decibels)...
