Question 1
In frequency-response analysis, what is usually described by the plot of a system’s response versus sinusoid frequency?
Question 2
For a typical low-pass system, what happens to the output magnitude as the input frequency increases well above the cutoff region?
Question 3
What does an output phase of $-90^\circ$ mean for a sinusoidal input?
Question 4
What is the gain crossover frequency?
Question 5
What is resonance in a frequency response?
