Challenge Problems
Push your limits with advanced challenges
A signal shows two distinct frequency peaks at 10 Hz and 50 Hz, but due to leakage, only a peak at 40 Hz is observed in the spectrum. Discuss how this misrepresentation can critically impact the application in monitoring.
💡 Hint: Consider what happens when frequencies that signify problems are masked.
Given a signal sampled over a short duration with a specified sampling rate, calculate the expected frequency resolution and discuss the potential impact of leakage in this context.
💡 Hint: Relate the sampling and duration terms back to resolution in frequency analysis.
