# (Originais Teachy 2023) - Question Medium of Physics

A team of scientists is developing a new communication device that uses both analog and digital signals. The device uses an analog signal of frequency 500 Hz to transmit voice data and a digital signal of frequency 3500 Hz for text data. The scientists have decided to use a medium that has a speed of wave propagation equal to 1500 m/s for both types of signals. If the wavelength of the digital signal is 3 times the wavelength of the analog signal, what is the wavelength of the analog signal in meters?
a.
3 meters
b.
1.5 meters
c.
6 meters
d.
9 meters
e.
12 meters

Question 1:

Easy

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 an analog signal at a frequency of 98.5 MHz. One day, the radio station decides to switch to a digital signal. The radio station wants to make sure that the digital signal has the same frequency as the analog signal. How would the radio station convert the analog signal's frequency into a digital signal?
