Challenge Problems
Push your limits with challenges.
Question 1
Consider a continuous-time signal x(t) = cos(2Οft). Compute its CTFT and describe the result in terms of frequency representation.
π‘ Hint: Use the definition of cosine in terms of complex exponentials.
Question 2
Explain how one might visualize the result of a CTFT for a complex signal composed of multiple sinusoidal components, e.g., x(t) = sin(2Ο5t) + sin(2Ο15t).
π‘ Hint: Draw the peaks on a graph to represent the magnitude of each frequency component.
