Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

If you double the signal power while keeping the noise power constant, how does the SNR change? Provide a calculation and explanation.

💡 Hint: Think about how the logarithmic properties work when signal power changes.

Challenge 2 Hard

A communication system detects a high level of interference which creates a noise power of 10 mW. If a user has control over signal power, which strategies could they use to enhance the SNR?

💡 Hint: Consider the ways to make the desired signal stand out more.
