Current limiting input differential Rs of 1M into a 10M INA with clamp diodes make this a simple task.
Any time you have a dielectric interface ( ___ pF ) source resistance will always have an error in signal response until the electrode impedance is eqal or less than the sub-cutaneous impedance. T...
The thermal noise of a resistance depends only on that resistance. However, there is always some parasitic capacitance. That capacitance against the resistance causes a low pass filter. So in a ...
In EMG there is a certain level of thermal noise created at the electrode-gel-skin interface which depends on the skin-electrode impedance (also known as source impedance). I have been able get th...
Serial communication protocols require synchronization of the clock of the connected devices. From GR the time elapsed for the satelite is different than the time elapsed for us here on the Earth....
I am designing a control system controlled by some microcontroller K: The open loop gain is $G_{o}(s) = \frac{K}{s(s^{2}+4s+3)}$ and the closed loop gain is obviously $G_{c}(s) = \frac{K}{s(s^{...
I know that many JFETs parameters have a very large manufacturing spread, in particular, $I_{DSS}$ and $V_{GS(off)}$, as one can see (for example) in this datasheet excerpt: ... My question i...
Introduction Yes, all those terms denote the same concept, that of differential (or incremental, or dynamic) parameter of a device. In the following I will explain such a concept initially in the...
I'll let someone else answer about the device physics. I'll answer from an electrical engineering standpoint. The answer is: Maybe, but it doesn't matter since you should be considering worst cas...
RG58 cables come in different variations, even with Teflon dielectric suitable for 200°C operations. Your cable, being suitable for up to 80°C, seems to be one of those with a PVC jacket and Polyet...
One of the main reasons was hinted by Olin's answer, at the end, when he spoke about non-linearities. The same is hinted in the excerpt in Nick Alexeev's answer ("they would overload the player amp...
Most of the issues have been discussed by other answers. However I would like to clarify something about pure water (a.k.a. "distilled water" or "demineralized water"), which is "apparently" not a ...
To truly "open circuit test" a motor as I interpret it, remove it from power, and measure the following: Using an Ohmmeter, measure each winding resistance. Start from W1 to W2. This will be...
I think we should definitely allow technical terms translations, because it's really difficult to find reliable sources online. And the translation process can be tricky, since the translated term ...
I agree with Olin and Mu3 answers. I'll add that you should aim not for just one kind of "high level" component, but many more basic ones. Not every EE course is the same across the world, and man...
Noise can be coupled between signal lines through parasitic capacitance formed between these signal lines, as $i = C\frac{dv}{dt}$ where C is the capacitance between the signal lines. Another wa...
Many ESD problems are "latent" that is they do not sofort show up....some time later things will stop working :)
The difference between your two options is which polarity the input floats to when left open, and whether there is an overall inversion. Adding the inversion in the firmware would require one more...
I want to sense 3 different states in the same mcu pin (GND, Hi-Z and PWR). PWR is typical +24V but I would like to have a wide margin from +17V to +40V just to be safe. The values can change but ...
First, the time dilation experienced by a satellite is tiny on a human scale. It takes sophisticated algorithms and lots of processing power to measure time differences between a spot on earth and...
The section you quoted says: "by injecting a small amount of current into the ground". With a solid ground connection, the voltage on their ground pin shouldn't change no matter what current is in...
I stopped trying to read your equations after the second undefined term. In general, start analyzing such things assuming switches, diodes, and the like are ideal. Also consider continuous and di...
I'm going to guess that by "PT100" you mean a positive coefficient temperature sensor with a nominal resistance of 100 Ω at 0°C or 25°C. Whatever it is you mean, it should be in your question. Th...
It all depends on what is connected between the main board and this "hat" board. Your schematic doesn't show any of these connections, so we can't really tell. In the end, the high current loop s...
When placing traces on this ground plane, is it better to Keep them as tightly packed as possible, grouping them into a concentrated "island" within the ground pour (Image 1)? Space them out slig...
