Hello All,
I have been playing around with this digital oscilloscope and function generator that I am using at school. I first connected the function generator directly to the oscilloscope to get the hang of adjusting it, then I took a small coil I had laying around and connected it in parallel with the function generator and scope to see what the voltage waveform over the coil looked like.
I ran through a wide range of frequencies and I noticed that some frequencies caused the voltage to rise a lot higher than the majority of other frequencies. Is this a good method to figure out what the natural resonant frequency of the coil is for use in an oscillator circuit, or would the coil itself need to be connected to a capacitor in an LC setup to find the resonant frequency?
I'm trying to build some oscillator circuits but I wanted to pick the capacitor value based on whatever the natural frequency of the coil happens to be (for now). But can I use my oscilloscope and function generator in the fashion I described above to find that natural frequency of my coils?
Thanks,
Jason O
