13.10 NORMALISED POWER IN A PERIODIC WAVEFORM AND
PARSEVAL’S THEOREM
The concept of normalised power in a periodic waveform is often employed in
Communication Engineering and allied areas as a measure of signal strength. It is defined
as the average power that will be delivered to 1 Ω resistance if the periodic waveform is
thought of as a voltage waveform applied to that resistor. The averaging is done over any
interval equal to the period of the waveform.
(13.10-1)
If we think of v

(t) [v(t)]
2
as a new time-function, the term on the right side of
Eqn. 13.10-1 can be identified as the DC component of v
3
(t). Hence, P
n
must be equal to the
exponential Fourier ...
