    Square Wave through a transformer, help diagnose this waveform?

    @Klaus thanks for the information. I see now that the inductor and resisitor act as a and RL differentiator and behaves exactly as you describe. Is there a pulse shape that will get the most energy coupled into the system, how would i go about determining that? Thanks, -Erik

    Square Wave through a transformer, help diagnose this waveform?

    @audioguru, thanks for the input. ill go run that test right now, ill let you know what the outcome is... Ok so yeah, around 100kHz i get a much better looking signal. However the coaxial cable i am using has a bunch of attenuation at higher frequencies so i am trying to keep my frequencies low...

    Square Wave through a transformer, help diagnose this waveform?

    Here is a schematic. @audioguru, all signals are the same frequency 10kHz, The 4th trace is the received signal at the other transformer. The middle 2 traces are the output of the filter on the receiving side. I believe the jitter seen there is caused by inefficient coupling of the signal to...

    Square Wave through a transformer, help diagnose this waveform?

    hey all, I am working on a project and i am having an issue i hope you can help with. I am driving a square wave signal into a primary of a transformer and using this to inductively couple a signal into a power line, in this case the power line is only 12v. The output of a processor is used...

    Trying to quantify attenuation with Function Generator

    Thanks Chuckey, your explanation helped immensely. Everything makes sense now. Thank you all for your help. Have a wonderful weekend, -ErikG

    Trying to quantify attenuation with Function Generator

    Thanks. That makes sense about the LPF having a different roll off curve. It is something i modeled in LTspice. The current state is (B). The resistor and capacitor was added together, as was the 50 ohm load. Here is my schematic: I hope this helps -Erik

    Trying to quantify attenuation with Function Generator

    Hello all, I am trying to verify if me theoretical predictions for a low pass filter match the real world attenuation. My setup is a function generator, outputting a sine wave at 1Vpp, which with no load is really 2Vpp. The generator is connected to the input of my low pass filter. Just a...
