Question 1
What is the dynamic range of a communication system?
- The power level of the strongest signal
- The difference between the smallest and largest detectable signals
- The frequency range of the signals
💡 Hint: Consider what 'dynamic' refers to in this context.
Question 2
True or False: A higher noise figure translates to a better ability to detect weak signals.
- True
- False
💡 Hint: Think about the relationship between noise figure and noise floor.

Challenge Problems
Push your limits with challenges.
Question 1
A receiver operates with a noise figure of 2 dB and a bandwidth of 5 MHz at 290 K. Calculate the noise floor. Then, discuss how this affects its ability to detect signals.
💡 Hint: Don’t forget to use Boltzmann's constant and consider the relationship with bandwidth.
Question 2
Design a hypothetical RF system that improves linearity by 5 dB without adding noise. Discuss potential trade-offs in terms of complexity and cost.
💡 Hint: Think about component selection and system architecture.
