Waves: Analogic and Digital Signals

Medium

(Originais Teachy 2023) - Question Medium of Physics

You are a scientist working on improving telecommunication systems. You have been investigating the differences between analog and digital signals in order to decide which one would be best for transmitting data over long distances without losing information. Considering the fundamental principles of analog and digital signals, explain why you would choose one over the other for high-quality, long-distance data transmission. Consider the ways in which these signals are transmitted, received, and processed, as well as how they respond to noise and interference.
a.
For high-quality, long-distance data transmission, analog signals would be the preferred choice due to their ability to be transmitted without the need for compression.
b.
For high-quality, long-distance data transmission, analog signals would be the preferred choice due to their continuous nature and ability to carry more information.
c.
For high-quality, long-distance data transmission, both analog and digital signals would be equally effective as they both have their own advantages and disadvantages.
d.
For high-quality, long-distance data transmission, neither analog nor digital signals would be effective due to the inherent loss of information over long distances.
e.
For high-quality, long-distance data transmission, digital signals would be the preferred choice due to their resistance to noise and interference, their efficient transmission and processing, and their ability to be reproduced exactly, ensuring no loss of information over long distances.

Imagine you are sending a message to your friend over a walkie-talkie, which uses an analog signal, and also texting the same message to the same friend, which uses a digital signal. Can you explain the differences in how the analog and digital signals carry and deliver your message? Consider the characteristics like continuous variation in analog signals and discrete values in digital signals, the effect of noise in the transmission, and the role of binary code in digital signals.

A radio station is broadcasting music at a frequency of 100 MHz. This analog signal is being converted into a digital signal by an analog-to-digital converter (ADC). The ADC samples the analog signal 200,000 times per second. If this digital signal needs to be converted back into an analog signal, a digital-to-analog converter (DAC) is used. However, the DAC in a particular radio receiver only samples the digital signal 150,000 times per second. What effect would this discrepancy in sampling rates have on the quality of the music being played on this radio receiver?
