Main Concepts
Fourier Transforms and the frequency response of a system.
- $ Y\big(\omega) = H(j \omega) X(\omega) $
Fourier transforms can be used to neatly and easily find the frequency response of a system.
Exercises
Tricky Fourier Transform
Compute the Fourier Transform of u(t-3)
Dealing with Differentials
Given:
- $ \frac{d y(t) }{dx} + 4y(t) = x(t) $
- a) What is the frequency response of the system?
- b)What is the unit impulse response (h(t)) of the system?
