What you ask is not specific to the Electrical Engineering site. There is nothing we can do about it here. If you really think this is a good idea, then you should propose it on the main Codidact...
I saw this link by accident and, while Andy's and Olin's answers are spot on, I thought I'd expand a bit on the complications they describe, just so you know what you're missing (or meeting, should...
The current applicable rule from https://electrical.codidact.com/help/topics would be: Off-topic ... High-level use of electrical devices. If your question treats a device like a black box and isn...
First of all, it depends on how much work the customer has done in advance. Do they have a proper spec? Do they at least have a bunch of key requirements? Or is it just "out there" and you must dra...
The worst case won't get any better, whether series, parallel, or some other combination. The result of two 1 kΩ ±5% resistors in series is a 2 kΩ ±5% resistor. The probability that the result is ...
I've heard that input signals to digital circuits should be "de-bounced", at least sometimes. What is de-bouncing? Why is it needed? When is it needed? What is bouncing around in the first place?
A differential amplifier and a differentiator are two completely different circuit blocks. Differential Amplifier A differential amplifier has two inputs and one output. It takes the difference ...
Your question is impossible to answer without carefully looking at the layout and schematic. However, from gut feel and experience, this smells like poor grounding design. Common mistakes: Not a...
I am looking at the datasheet of the 7508170315(link) transformer and something seems strange to me. If I connect this to a 12V supply and expose it to 10us pulse: 12V*10us/475uH = 252mA which ...
In the image below is an opamp buffer with +/- 15v rails connected to a 3.3v ADC. The input to the opamp is limited to 0-3v. There is no protection circuitry for the ADC. Is the risk of the opam...
If I connect this to a 12V supply and expose it to 10us pulse: 12V*10us/475uH = 252mA $$$$ This current flows in the primary magnetization inductance (475 μH) after applying 12 volts for 10 μ...
Is the risk of the opamp overdriving the ADC too great for no input protection to be used? I would certainly say yes but, this can usually be easily solved by using a current limit resistor in...
Is the risk too great? That depends on parameters you haven't told us. How cost-sensitive is this product? What is the reliability expectation of the users? How mission-critical is its usage? ...
A little check list of some basic things to ask yourself before asking such a question: Is this some manner of high/mains voltage device? Repairing such electronics is very dangerous if you don'...
Digital voltmeters generally display decimal digits. The resolution implied by that is not necessarily the same as the underlying binary A/D. Since voltmeters for human display don't need to be f...
The display counts range is one of the digital multimeter characteristics. We know that a DMM is based on an analog/digital converter, and we know too that each ADC has a certain resolution in bit...
Here is a solution to protects very well the ADC from over-voltage spikes, avoid any simulation and design consideration, and that also protects the ADC from a possible negative output spike from t...
Every time I needed CAN, I had just put external crystal and didn't think about it after that. It worked fine. I am wondering however whether the precisions of MCU internal oscillator is sufficien...
It's still unclear what you are really asking, so I'll discuss the tradeoffs between low and high side switching of power to a load. Low side switching The main advantage of low side switching is...
You are making this too complicated. The only thing that matters is the percentage mismatch between any two clocks on a CAN bus. You seem to imply that you are willing to guarantee the -10 °C to ...
In the circuit below, I am applying a $3.3Vpp$, $63kHz$, 50% Duty Cycle, PWM input signal at the gate of the mosfet and I am expecting to see a similar waveform with different amplitude at the LED...
In addition to the previous considerations, I will add a few more. Stages with voltage output (such as a voltage follower) are implemented as voltage dividers consisting of two elements in series "...
Recently I had opened an remote control (RC) toy to see its circuit and found that it operates on 27 Mhz. Not just that toy even many toys operate in that 27 and 49 Mhz band. These days we find eve...
You are asking for a filter that passes 2% at 60 Hz and 99% at 90 Hz. That comes out to a transition of 97% of the amplitude within 0.6 of an octave, which is quite aggressive. The real answer My ...
