Challenge Problems
Push your limits with challenges.
Question 1
Consider a signal represented by f(t) = cos(2πft). If this signal’s timing is shifted by t₀, analyze the effect on its Fourier Transform.
💡 Hint: Examine each term in the original signal's Fourier representation for transformation.
Question 2
Analyze the time-shifting property in a practical scenario where signal delays affect system feedback, resulting in instability. How can understanding this property aid in design?
💡 Hint: Relate the time shift effects to feedback loops and examine stability techniques in engineering.
