Just wanted to verify some newbie queries.
If I have a Sinewave that is 100mA peak to peak but the lowest amplitude of the signal starts at 20mA & ranges to 120mA.
The signal is all positive voltage from +20mA to +120mA so it is not an AC signal but more like a big DC ripple.
What Terminology is used to describe the signal, is it just a DC signal.
With a signal as mentioned, is the Peak to Peak terminology correct or is that term only used for AC signals where the signal is above & below 0V.
Is the rms value still calculated the same as an AC waveform or do you average out the signal strength somehow.
Do I just calculate the rms from the peak of 120mA even though the signal itself is 100mA Peak to Peak due to the 20mA floor.
Not sure if any of it makes sense.
Cheers
