I have a normal coil. I'm going to send a clean 22V @ 1A square pulse into the coil. whatever frequency, say 2 hertz. So the coil will charge and discharge every two seconds.
If I scope the coil it will look like <snip>. How can I keep the integrity of the square pulse high, like if I scope the coil the waveform will look like <snip>. I'm trying to keep the pulse going in (and coming out) as clean as possible. Any tips for a novice? I need to bridge the connectors of the coil with a diode to stop the back emf from discharging back into my circuit right? any recommendations on the proper diode for that? Just seems the more I pulse the uglier the square wave becomes. Maybe I'm not suppose to put the coil on the scope directly, should have a resistor?
Sorry my question is kind of obscure.
Thanks.
