Step-by-step explanation:
What happens to a digital signal sent using electromagnetic waves as it travels farther from its source?
Solution.
To transmit a signal, the analogue signal is first modulated and converted to digital signals.
The digital signals transmitted through electromagnetic waves like radio wave or microwave can experience attenuation over a long distance as they tend to pass through tissues and wall.
The frequency and the intensity of wave continue to decrease as the wave tend to propagate through the wall and tissues.
To correct this, there must be a device to amplify the signal at the strategic points.
After this, the signal will be demodulated back to the analogue signal.
Therefore, attenuation may occur as the signal tend to pass through the tissues and office walls.
