When posting identification or general questions related to connectors, integrated circuits or other parts with pins/legs, engineers always speak about something called pitch. What is the meaning ...
200 HP is 147.1 kW. At 480 V, it takes 306 A to transfer that much power. You didn't say, but your 480 V power feed is probably three-phase, and the motor is three-phase too. I don't remember ho...
is there a technical reason that prohibits such cable from working? Two reasons: Signal integrity Data integrity Signal integrity is reason #1. Basically, cables are not "transparent"...
I've figure probably not an IGBT since their gate requires too much current, while a BJT would be too wasteful as well, so would that mean a MOSFET or JFET is the best choice? First, let's cla...
You need something with very low on-state voltage drop. That effectively means some type of FET. Those look resistive when on, as opposed to a voltage source like a BJT does. You need to look ca...
In the ADC datasheet(link), there is a following schematic snapshot for interfacing the ADC differential input channel with the Current Transformer: Furthermore, Two identical burden resistor...
That depends on whether you are just building something for yourself, say a prototype, or if you are designing a product for mass distribution. In the later case, you are subject to probability law...
My Answer: There are only practical reasons for a representation with Ib=const. These characteristics are primarily used to determine the DC working point (Ic_o, Vce_o) - together with the working ...
I think this could be on topic if done carefully. We don't want this to devolve into a popularity contest of everyone's favorite features. Answers also can't be about opinions of which features "...
What happens to the overall accuracy of a resistor if I implement it as multiple resistors in series or parallel? For example, can I get better than 2 kΩ 5% by putting two 1 kΩ 5% resistors in ser...
The default scope in this EE community pretty much went with the same scope as the SE site. For now. These sites are new and most communities are still struggling to come up with what's off-topic ...
Eureka! thanks to the article cited in the question, I've finally understood the matter. I will describe here the general procedure for computing the network parameters of a grounded two port devi...
Baudrate is most often used to mean payload data bits/second. Simply picture a manchester encoded protocol, where each data bit corresponds to 2 physical bits in the raw data frame. If you have a b...
[In addition to the answers which have already been posted.] A current sensing circuit like this lends itself to another scheme for ESD protection, which uses only one TVS. Only the line in which...
I'd like to use a 555 timer as carrier wave generator at ~ 50 kHz and modulate the amplitude with an external digital signal at ~ 1 kHz. The pulse width remains constant at 10us (50% duty cycle)....
It's kind of surprising that the TVS diodes dumping ESD into the GND plane don't affect the microcontroller; however, if the shield dumps ESD into the GND plane it has a very strong effect. Th...
PCB's and components are expected to be used with the common SAC solder, there's little reason to use SnPb, IMO. I learned on SnPb. After a brief transition for RoHS to re-calibrate the "feel" of i...
In circuit analysis why always the power has upper hand over energy? Even if we consider a simple battery circuit with a bunch of resisitors we always use the terms power delivered,absorbed,consump...
I just want to know why the Linear time-invariant(LTI) systems are a rich class in Signal Processing. Ofcourse there are different systems but still LTI is stressed a lot in academia. Is there any ...
We can now support changing the reputation values for papers, if this is what the EE community would like. Here's how it would work. We can't currently vary properties of post types per category, ...
The turntable is apparently run by a cheap synchronous motor. There is a type of motor that's easy to manufacture, that turns synchronously with the line frequency. You say the table used to rota...
In the block diagram of this pulse oximeter design guide , in page 6, I see that the system utilizes two analog filters, one for filtering the PPG signal generated while the RED light/wavelength is...
UPDATED. based on clarification to original question. To be clear, just an idea, not tested for this situation! It is abusing the V_I_L margin on the 3.3V CMOS input, so series diode should be sc...
I want to run a specific motor in the open loop. How to calculate the maximum ratio of V/f to run it? Am I looking at Ld or Lq value for this? Let's say these are the characteristics - haven't ch...
I am trying to design a full adder in SystemVerilog. I searched on Wikipedia and I found this https://en.wikibooks.org/w/index.php?title=Microprocessor_Design/Add_and_Subtract_Blocks module full_...
