What is an advantage of having a variety of receiver bandwidths from which to select?
The correct answer is C: Receive bandwidth can be set to match the modulation bandwidth, maximizing signal-to-noise ratio and minimizing interference. What is an advantage of having a variety of receiver bandwidths from which to select is that receive bandwidth can be set to match the modulation bandwidth, maximizing signal-to-noise ratio and minimizing interference. Matching bandwidth optimizes performance. For amateur radio operators, this is important for receiver operation. Understanding this helps when selecting bandwidths.
Exam Tip
Variety of bandwidths advantage = can match modulation bandwidth, maximize SNR, minimize interference. Think 'V'ariety of 'B'andwidths = 'V'ersatile 'B'andwidth matching. Matching bandwidth optimizes performance. Not noise figure adjustment, not power consumption, not multiple frequencies - just bandwidth matching.
Memory Aid
"Variety of bandwidths advantage = can match modulation bandwidth, maximize SNR, minimize interference. Think 'V'ariety of 'B'andwidths = 'M'atch modulation. Matching bandwidth optimizes performance. Important for receiver operation."
Real-World Application
Having a variety of receiver bandwidths: An advantage is that receive bandwidth can be set to match the modulation bandwidth, maximizing signal-to-noise ratio and minimizing interference. For example, narrow bandwidth for CW, wider for SSB. This is the advantage - bandwidth matching optimizes performance.
Key Concepts
Why Other Options Are Wrong
Option A: Incorrect. Adjusting noise figure of RF amplifier isn't the advantage - matching bandwidth optimizes SNR and minimizes interference. Noise figure adjustment isn't the advantage.
Option B: Incorrect. Reducing power consumption isn't the advantage - matching bandwidth optimizes SNR and minimizes interference. Power consumption isn't the advantage.
Option D: Incorrect. Receiving multiple frequencies simultaneously isn't the advantage - matching bandwidth optimizes SNR and minimizes interference. Multiple frequencies isn't the advantage.
