Transcribed Image Text:C)
d)
Another periodic waveform is defined by
4t
7
= 0
g(t)=
0<t<T/2
T/2≤t<T
with g(t+mT) = g(t) and m is an integer.
Sketch g(t) over three full cycles in the time domain, labelling axes.
Show that the complex Fourier coefficients of the periodic waveform
g(t) of Q1(c) are given by
_ (-1)³²-¹+; (−¹)² (n=0)
n²x²
PIT
e)
Use the complex coefficients derived in Q1(d) to derive the first four (non-
zero) terms of the real Fourier series for g(t).
