What we call this opamp configuration? A mess. What's the advantage and the disadvantage of this circuit? This can't be judged without the stated objectives. It might be useful for keepi...
If there isn't a VA rating on the label or published in a reliable source, then you have to guess. There are several clues that can be used: Look at the size of the primary wires. That gives you...
In protocol I2S we have 4 signal: 1.data 2.lrck/fck (frame synchronizer) 3.bck (bit clock) 4.mck/sck (master clock) Not really. IIS really only has 3 signals: bit data, bit clock, and left/right ...
Your basic problem is that the motor needs some applied power to generate any EMF, but if you apply that power then its not an open circuit test. For a true induction motor you're probably stuck. ...
Adding to what Lundin said (+1): s is seconds, S is siemens (1/Ω). What we write here is inherently HTML. Greek characters like µ and Ω are defined as HTML entities, and can always be writte...
CAN lines in the most common implementation have 60 Ω impedance between them. Anything that is substantially larger than that won't effect the lines much. I'd use 1 kΩ at least, preferably more. ...
First, common mode is something that only applies to a differential signal. When a signal is encoded in the difference between two voltages, the common mode voltage is the average of the two. The...
I've never been involved with the design of an ESD table, so I can only imagine some reasons to put grounding connections at the front: For convenience. If you've got a table specifically for ESD...
They don't outright tell you the maximum operating voltage, probably because that would imply a power level beyond what they think anyone would use this connector with. Note that it is intended fo...
Some optos are really slow. What off time is yours specified for? Your circuit could be better. The transistor is turned on thru 1 kΩ, but off thru 11 kΩ. You are also giving it way more base c...
The voltages from the raw microphone are quite small and fairly high impedance. That's why an amplifier at the mic is needed in the first place. The signal on the wire would be way too small comp...
Talk to your board house. 4 mil slop for the soldermask around pads is excessive. Leaving 4 mils is fine for larger parts, but as you say, it doesn't work for fine pitch. The main reason for mak...
Microwave ovens work on the frequency they do because that's one of the main resonant frequencies of water molecules. The radiation excites water molecules, which then transfer some of their extra...
pure stable sinusoidal wave This is impossible. Forget it. Go home. No matter what you do, there will always be some noise added to the sine wave. Some random noise and some harmonic distortio...
