WebOct 4, 2024 · The cutoff frequency is defined as the frequency where the amplitude of H (jω) is 1√2 times the DC amplitude (approximately -3dB, half power point). Solve it for ωc … WebThe cutoff frequency is defined as the frequency for which the resistance of the resistor equals the reactance of the capacitor. At that point, the signal is .707 times the original amplitude or reduced by 3db. Above the cutoff frequency, the signal falls by 6db per octave. Below that point (in the passband) the signal is unaffected.
