Can you tell me why we are using 50 ohm impedance for single ended?
Is it because of cable having 50 ohm only?
also the reason for using 75, 90, 100 ohm impedances ..
y not we use 100 ohm for USB?
What is the exact difference between resistance and impedance?
If impedance mean for the restriction of AC current, why we have to consider it for DC.?
