Frequency Response, Nyquist And Bode Diagrams Flashcards
1
Q
What is the frequency response of a system
A
The steady state response of the system to a sinusoidal input signal
2
Q
What is the frequency response function
A
The output phasor divided by the input phasor
3
Q
What is the phase crossover frequency
A
The frequency at which the phase angle first reaches -180 deg
4
Q
What is phase margin
A
The angle in degrees by which the phase angle is smaller than -180 at the gain crossover
5
Q
What is gain margin
A
The factor by which the gain must be multiplied at the phase crossover for the magnitude to have a value of 0 dB
6
Q
What is gain crossover frequency
A
The frequency at which the magnitude had the value of 0 dB
