How does the pulse detector coil and damping resistor smooth the waveform？

How does the pulse detector coil and damping resistor smooth the waveform？
I tried to change the damping resistance and re-create the coil, which did not achieve the results I needed. How can I do it?

Your question is very broad, you need to supply the technical and electrical specifications of the circuit you are trying to make work .

[Carl-NC]

Or just re-phrase the question. What do you mean by "re-create"?

In the same size (30cm circle) to make different parameters, I have 310uh, 1.9ohm, is a 0.5mm cable shield, 20 core, t1 waveform is not smooth enough, the depth difference.
Ps: is the legend of the pulse of kt.

A pulse detector, how to match the coil data and damping resistance, one of my making 30cm circle, 310uh, 1.9ohm, using 20-core cable, 0.5mm wire diameter

Now we have some information to work with, thats the delta pulse, the expert to ask is KT315.

look on this GIF and try turn your imagination.

Yes, the last moment in the animated GIF is what I want. I try a lot and I haven't reached it. What should I do?

My coil is a 320uh, 1.9 ohm, 30cm circle

Thx kt315, a good example

you must variable THE damp resistor value and LOOK on the screen of your oscilloscope. set o-scope probe on OUTPUT of preamp.

If not smooth enough to continue to reduce the damping resistance? I did 200ohm and I didn't get the best!

[wyl123]

I use about 50ohm, the waveform is smooth, but the depth is very poor, only a 20cm can!

Bad depth！

what you mean is not BEST? those asiatics women around you are best? LOL ))) begin from 2k2 - give the pic
1k - give the pic
820 ohm - give the pic
680 ohm - give the pic
