Analog Signal Changes Over Time

“An analog signal representing a sound wave has an initial amplitude of 5 volts. Over a period of 10 seconds, the amplitude fluctuates between 3 volts and 7 volts. Describe how this variation in amplitude over time might affect the quality of the sound being transmitted. A radio station transmits an analog signal that varies in frequency from 88 MHz to 92 MHz over a period of 15 seconds. Explain how this change in frequency over time could impact the clarity of the audio received by a listener.”
