Hello everyone,
The given problem of mine is the eq'n x(t) = t/T, for 0<t<T, where T
is the fundamental period.
The time 0<t<T represents the first tooth in the periodic sawtooth
waveform.
I'm using the Fourier Series form:
X(t) = sum for n=-inf to +inf {Cn*e^j2*pi*n*f*t}, n=0, +\-1, +\-2, . .
..
Where,
Cn = 1/T*integral_over-T{x(t)*e^-j*2pi*n*f*t}
I come out with a 3 termed eq'n for Cn. One of the terms is
1/(2pi*n)^2. As the Fourier series is from n=-inf to +inf, the DC
component(when n=0), will make that term infinite.
Can anyone steer me in the right direction as to how I can find the
amplitude and phase spectrum of this problem? I know it's simple and
I apologize, but I've been at it for hours.
Thanking you in advance,
-Arthur
