rms value of ac signal [sine wave] at 0 dc level is 0.707 Vp
if wave is shifted at 3 V dc level the
is rms value remains same?? :idea:

shaw said:thanks for reply
i know this fact i want to confire
clamper circuit shift the wave at some dc level whereas input has 0 dc level
then is it not violated the law of cinservation of energy?
what physically rms value of a signal means?
can we say that it is energy of a signal?
please explain :shock:
fsahmed said:MAthematically, RMS is a rather more accurate way of average finding,
REgarding electricity, the RMS value of AC represents the value of DC that would be required to produce the same heating (energy transfer) as the AC whose RMS value u have calculated. A 312V AC would produce the heating effect of only 220V DC.
fsahmed said:Add the RMS value of the AC component to the DC. Thats about it.
shaw said:i still have confusion about energy of a signal
please explain

please explain
energy is just the sum of the power (or the integral over time of the power)

_3iMaJ said:Thats what the power spectral density explains.
Just look at the integral. Its the integral of the absolute value squared of the transfer function multiplied by the fourier transform of the input function integrated over all frequency.

WHAT?
