Challenge Problems
Push your limits with advanced challenges
Consider a system that samples signals at 30 kHz. Identify the Nyquist frequency and discuss the implications if the signal contains frequencies up to 15 kHz.
💡 Hint: Calculate the Nyquist frequency and assess the original signal's frequency.
A telecommunications system is designed to handle frequencies up to 25 kHz. Calculate the minimum sampling rate and discuss the impacts of aliasing if the system only samples at 40 kHz.
💡 Hint: Use the formula for Nyquist sampling and consider what happens with lower rates.
