**Reading:** Chapter 4, Sections 4.3 to 4.6.

**Problems:**

- 1.
- Find the Fourier transform of the functions and
using the
*definition*of the Fourier transform, not the table. (Hint: Recall the ``sifting'' property of impulse functions.) - 2.
- Sketch , , and .Label the amplitude at
*t*=0 and the zero-crossing points. - 3.
- Sketch .Find the inverse Fourier transform
*x*(*t*) using the tables, and sketch*x*(*t*). - 4.
- What is the Fourier transform of ? Sketch the 2-sided amplitude spectrum.
