Modulation
Modulation is a fundamental process in satellite communications where information (like voice, data, or video) is prepared for transmission through space. Think of it like packaging information into a format that can travel efficiently through satellite signals. It's similar to how radio stations encode music onto radio waves, but for satellite communications. When you see this term in resumes, it usually indicates that the candidate has experience working with satellite signal processing and transmission systems. This is a key skill in satellite communications, telecommunications, and broadcasting industries.

Example Interview Questions
Senior Level Questions
Q: How would you explain the trade-offs between different modulation schemes in satellite communications?
Expected Answer: A senior engineer should be able to explain in simple terms how different ways of sending signals through satellites affect things like signal quality, power usage, and data speed, and how to choose the right method for different situations.
Q: What experience do you have in optimizing satellite communication systems?
Expected Answer: Look for answers that show they've improved satellite system performance, reduced signal problems, and made systems more efficient while managing teams and projects.
Mid Level Questions
Q: How do you troubleshoot modulation-related issues in a satellite communication system?
Expected Answer: Should describe a systematic approach to finding and fixing signal problems, using testing equipment, and working with both ground station and satellite equipment.
Q: Can you explain how weather affects satellite signals and how to handle it?
Expected Answer: Should be able to explain in simple terms how rain and weather can affect satellite signals and what methods they use to maintain good signal quality despite these challenges.
Junior Level Questions
Q: What are the basic types of modulation used in satellite communications?
Expected Answer: Should be able to explain the basic ways that information can be sent through satellite signals in simple, non-technical terms.
Q: How do you measure signal quality in satellite communications?
Expected Answer: Should demonstrate basic knowledge of signal quality measurements and common tools used to monitor satellite communications.
