Solution: Given ( x(t) = A \cdot \textrect(t/T) ). Step 1: By definition, ( X(\omega) = \int_-T/2^T/2 A e^-j\omega t dt ) Step 2: Integrate = ( A \left[ \frace^-j\omega t-j\omega \right]_-T/2^T/2 ) Step 3: Simplify = ( AT \cdot \textsinc(\omega T/2) ) Step 4: Plot |X(ω)| vs ω for A=1, T=1 (see Figure 5.4).
