Let xa(t) be the half-wave rectified signal in Table 4.3. Let xb(t) be the same signal delayed by T0/2.

TABLE Fourier Series for Common Signals

(a) Find the coefficients in the exponential form for xb(t). Hint: Consider time delay.

(b) Show that the Fourier coefficients of the sum [xa(t) + xb(t)] are those of the fullwave rectified signal in Table.
