"React" implies a response to an "event". For an inductor, the "event" is a change in current, $\frac{di}{dt}$ For a capacitor, the "event" is a change in voltage, $\frac{dv}{dt}$ $$$$ So, ...
It seems like you did the reduction to a Thevenin source mostly right, although the final value is a bit off. The original circuit we want to reduce to a Thevenin source is: First we reduce V1,...
I'd rather use the AD4111 as a high-side current sensor, instead of creating an "inverter" which would generate an equal and opposite current. Each current input of the AD4111 (IINx+ and IINx-) is...
The 45° routing makes it easier to route multiple parallel traces across the PCB - I would say that's the main reason why they are so popular. Whereas 90° turns of multiple parallel traces next to ...
If you put the Fat load-dump TVS downstream of the reverse-polarity protection MOSFET [1], then the load dump current would have to flow through the MOSFET. The MOSFET would have to be rated for t...
Using a P FET for polarity protection like this means that in case you flip + and -, the gate will be inactive, meaning that GND which is now connected to drain will get disconnected - no current w...
I have a solar panel rated for 6V open-circuit and up to 150mA. I would like to connect this to an SPV1040 or similar buck-boost converter with MPPT functionality to be able to charge a 3.6V batter...
Hello, I am trying to use a CD4047 in monostable, positive-edge trigger mode: I am not skilled enough to make out what the output, i.e. pin 10, should be when pin 8, the input, is held at 0V (...
Lets say I power an oscillator by a non-rechargable battery. Lets imagine a generic design with LC-circuit and negative resistance created by some transistor circuit. To me it seems that at certai...
What does it mean for signals to have impedance? I expect that what it means is that a particular signal source has an effective series resistance (for a voltage source) or, an effective paral...
What does it mean for signals to have impedance? To me, impedance is kinda like an "extended resistance" that also includes phase shift $$Z = R + jX $$It makes sense to me that components like cap...
It is important to realize that an ECG signal is high impedance and this easily picks up line voltage E-fields. Using a 50 Ohm sig.gen. is a poor simulation of the use of this circuit and also neg...
Olin has a great answer, I just wanted to add some of my personal experience. I only started laying out PCBs three years ago, and I use KiCad. KiCad got curved traces support in test version 5.99 o...
The best route is a straight connection between the two points being connected. Of course that's not always possible due to other objects being in the way, or to be able to route other connections...
Most modern CAD software for PCB design offers arc trace routing or a form of conversion between 45/90 degree angel trace routing and arc trace routing. Despite this, the overwhelming majority of c...
To understand the timing, you must understand the cause. Delay is the time from input to output It is measured from +10% of input to 90% of output ( or a 10% change in output), unlike logic chips ...
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...
The specs you need from an opamp in an audio circuit are somewhat dependent on the particular circuit. As you state, requirements of good audio circuits are high signal to noise ratio and low dist...
You best source of information is boilerplate on the part itself. you have that but all there is is a part number and the design voltage. Your next best information is the boilerplate on the appl...
It's a current limiter, not eliminator. The current is always supposed to flow, but be limited at startup to avoid high inrush current. All the relay does is short out R103 when activated. The r...
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...
