I got this question during a job interview.

This intriguing question comes from Ground Stations in portion Satellite Communication of Avionics

Answer 1

In the receiver section of a satellite communication system, a band-pass filter is used to allow signals within a specific frequency range to pass through while filtering out signals outside of this range. This helps in reducing noise and interference from unwanted signals, ensuring that only the desired signal is processed.

Final Answer:
