X(f) = ∫∞ -∞ x(t)e^{-j2πft}dt
Problem: Find the Fourier transform of a rectangular pulse signal. X(f) = ∫∞ -∞ x(t)e^{-j2πft}dt Problem: Find the
Problem: Design a low-pass filter to remove high-frequency noise from a signal. we can simplify the solution:
where T is the duration of the pulse and sinc is the sinc function. X(f) = ∫∞ -∞ x(t)e^{-j2πft}dt Problem: Find the
Using the properties of the Fourier transform, we can simplify the solution:
