Hi to all,
I'm trying to built simple power amplifier with cmos output. I need to calculate output power in tran analysis, usually I do it with dft function and rms value for signal.
For example for sinus we know:
\[P=\frac{V^2 }{2R }\]
Also, from wiki crest factor for rectangular waveform equal to 1.
Does it mean, that final equation for dft will be \[P=\frac{V^2}{R}\] ?
If so, what will happen if duty cycle isn't equal to 50% ?
