Display port eye diagram evaluation
I was testing my display port diagram, all 4 lines.
The first three look good, the 4th line looks like it has only one signal (not differential.)
My question:
Is the 4th line okey to be like this. (...

Which is preferred over differential pairs: trombones or sawtooths?
I have been told that trombones are much better to use than sawtooths, even if sawtooths may be prefered in some certians scenarios.
Here I have added trombones to the differential pairs. If I had ...

What is the single line waveform of a resolver of sin or cos output？
For a resolver, the excitation signal is about 10kHz sin waveform. And the output are two pairs of differential ports: sin+/- and cos+/-.
If I test the output signal(such as sin+/-) by using a ...
