Transcribed Image Text:2.1-5
If a periodic signal has the odd-symmetry property v(-1) = -v(t), then Eq. (14)
may be written as
To/2
| u(t) sin (27nt/T,) dt
C, = -)
Use this expression to find c, when v(t) = A for 0 <t< T/2 and v(t) = -A for
-To/2 < t<0. As a preliminary step you should sketch the waveform and deter-
mine co directly from (u(t). Then sketch and label the spectrum after finding cp-
