I've heard that arc welding is getting done with low voltage. I believe arcing requires high voltage. Then how is arc welding done with about 50 volts? I thought we need kilovolts for arcing. Why? ...
As we know audio has high dynamic range. It means 120dB dynamic range of human ear causes to hear 1 million time samaller that highest undistorted accoustic wave. Then I think for high end audio we...
In protocol I2S we have 3 signal + one none standard master clock(Mentioined by Olin Lathrop): 1.data 2.lrck/fck (frame synchronizer) 3.bck (bit clock) 4.mck/sck (master clock) Question 1: Why we...
The problem was the transient you can see in the first picture, the blue one. When I connect the scope to it, it becomes stabilized. Otherwise it is noisy and because of this the other signal chang...
PLL lmx2491 have OSCin pin to apply reference clock on it. It said it is differential. One famous differential is LVDS. It does not tell anything about it's compatible logic standards. It said: ...
Question 4 solved: The datasheet lacks the information I've copied from PCM5122:
I have a HANTEK 6022BE oscilloscope and I'm monitoring three signals with it: FS (Frame sync clock). Pulse. Transfer complete. I'm using two channels of the scope to monitor a pair of these...
Mini-circuits LNA PHA-LN13+ has suggested: Eval board Layout Eval Gerber The image took from the Gerber file (3rd ref.) (Though all 3-reference mentioned containing it): There I have som...
I've tryed to implement a local ground concept told by Olin Latrop here : He have told: (What I've perceived)You should not connect every gnd point instantly to gnd plane, since it can inject HF ...
