If I put a dc square wave into into a transformer, do i get a sine wave out the other side?
Probably one of the most unhelpful answers I've heard in a long while!An iron-lamination transformer will indeed act as a low pass filter -- however the 'DC' offset will cause both saturation and excessive primary heating...
I shouldn't think non-sentient objects could be said to 'know' anything --- Your statement seems to be a non sequitur?Does the transformer know whether the input is AC or DC
Plumber's revenge? Musical puzzles? --- So, are we talking a video game? --- Anyway - pleased you got your answer!Its ok I did learn thanks - I was just half joking around.
The musical puzzles led me to believe it depends if the square wave is ac or dc?
Very frequency dependent. I have seen transformers specifically designed to pass square waves inside a 1% precision machine, but they were not iron core. An iron core transformer can be taught to pass a square wave by applying the right capacitance in the right places, and in the right frequency range, but it will not automatically make a sine wave, just a sloppy square wave.Frequency dependent I suppose?
FWIW By way of avoidance of just such confusion the term 'Pulsating DC' is commonly applied to varying 'functions' having offsets preclusive of polarity inversion...Just because current doesnt pass 0 doesnt mean it isnt alternating, ill remember that for next time instead of confusing the lot of you with my inane gibberish and poor reading of the help provided.
