Exercises 3.8.2 Questions: Q3-2. What does the amplitude of a signal measure? What does the frequency of a signal measure? What does the phase of a signal measure? Amplitude: it measures the proportion of the energy that a specific area can carry it, and it always include (peak amplitude) which represent the highest intensity that carried by the area. Frequency: it used to measure “the number of periods in 1 second”. Phase: it is used to “describe the position of the waveform relative to time
