PL2.5: When you plot the frequency response of a filter (also known as a Bode plot), you will observe not only the magnitude but also the phase shift of the filter. Consider the response characterised over the frequency range spanning 10 Hz to 100 kHz. At the specific frequency of 1 kHz, what does the phase shift correspond to in terms of circuit functionality? Choose from one of the following:

Question

PL2.5:  When you plot the frequency response of a filter (also known as a Bode plot), you will observe not only the magnitude but also the phase shift of the filter. Consider the response characterised over the frequency range spanning 10 Hz to 100 kHz. At the specific frequency of 1 kHz, what does the phase shift correspond to in terms of circuit functionality? Choose from one of the following:

Answer

How much the filter attenuates the input signal at 1 kHz

Answer

Filter has a -3 dB cutoff frequency of 1 kHz

Answer

Phase shift is proportional to the delay experienced by the input waveform at 1 kHz through the  filter

Answer

Filter gain at 1 kHz frequency
