Hello ,
I'm making a dc motor control system , I have a control ct. and a power ct (H-bridge configuration) , the PWM control signals need to be transferred a long way to the power ct. in a noisy environment , when I used the oscilloscope to view the signals , I found the signals to be very distorted as shown in the figure when it reached the power ct. which caused fatal results .
I understand this is because the inductance of the cable , but I can't understand it mathematically and physically , can someone please illustrate it for me , and is there some way to prevent this kind of distortion ?
note: i use a shielded cable to transfer the signal
