Question 1 of 27070

Q

A ____ provides a very high degree of selectivity in a receiver:

🔍 Key Concepts

• Selectivity in a receiver – what does it mean in radio/electronics? • Different types of filters used in radio receivers (RF/IF stages) • How crystal devices behave compared to simple RC or LC filter components

💭 Think About

• Which of these components is specifically designed to allow only a very narrow band of frequencies to pass and reject nearby channels? • In a receiver, when you want to separate one station from another very close in frequency, which option is commonly used in the IF (intermediate frequency) stage? • Which choices are more about power supply/smoothing or broad frequency shaping, rather than sharp channel selection?

✅ Before You Answer

• Identify which options are actual frequency-selective filters versus general-purpose components. • Think about which device is known for a very narrow bandwidth and high Q (quality factor), giving sharp tuning. • Eliminate any option that mainly deals with DC supply stabilization or bypassing noise to ground, not channel selectivity.
