Yeah, that looks like it's going to be messy. I agree with Olin: the problem starts with three variables and three conditions so, no matter how you look at it, you will end up with a system of...
I don't know what the book has in mind, but your first point is the main reason I would want to filter out the high frequencies with passive analog components. Low noise and low distortion are imp...
I am looking to improve my knowledge of embedded systems programming, specifically regarding microcontrollers and embedded Linux systems. A lot of the information that can be found regarding C/C++...
What kind of IC can be used to drive the MOSFET, so that when the voltage drops below 6.2 V the battery disconnects from the load? That reverse protection MOSFET works fine for reverse protect...
The plugs for microphones and for earphones are the same, however their functionality obviously is quite different. Now because of the same plugs it is easy to insert one of them in the wrong socke...
I am using two 18650 cells in series to power a RC car. Is the voltage goes below 6.2 V, the battery should be disconnected to prevent over discharging the battery. At the same time I want to imple...
One possibility is to use a transformer. The power input can then come from across the plus and minus input power. The output can be referenced to whatever you like, which in this case would be g...
I am also not an expert, but have been working on designing a couple of products that need C1D1, C1D2, and some IS associated apparatus with some electronics consultants that specialize in these ce...
Most of the energy produced by the CT windings is being wasted in the internal burden resistor. See this data sheet to see what I mean. I calculate that it has a 60 Ω burden resistor and, at full p...
Hi guys so recently i was looking for a mosfet and a gate drivers and between a lot of their specification the rise/fall time and Turn-On/off Delay Time sometime it called propagation. My question...
Impedance Yes, impedance is "extended" resistance. Impedance is really a complex value, with resistance it's real part. The imaginary part represents pure inductance or capacitance (with opposit...
What are the advantages of such DC offset removal loop, compared to an RC high-pass filter? The primary advantage is that it keeps the front-end amplifier output centred in its DC operating re...
In addition to what Andy said, the DC servo method doesn't add impedance to the signal. Note that in your bottom circuit, the signal with the DC offset removed has an impedance of 1 MΩ at DC. In ...
I've heard that arc welding is getting done with low voltage. I believe arcing requires high voltage. Then how is arc welding done with about 50 volts? I thought we need kilovolts for arcing. Why? ...
It's a balance. On one had, we want to be a store of knowledge. It doesn't matter what prompted a particular piece of information to be posted if it serves the long term purpose. We also don't w...
At 1 MHz it's probably not transmission line effects. It's not clear from your question whether the SPI bus works on the main board with the expansion board connected, but not when it's not connec...
Your proposed circuit will work, but "before the voltage drops significantly" is rather wishy-washy. I would at least use a second meter to measure the current. What you really want to know is th...
Promote this site (or any Codidact site, for that matter) I don't have a great answer, just a perspective. I started using StackOverflow in the public beta in late 2008. I joined electronics.stac...
For high-speed digital communication busses, what attributes do you generally advise to add to a PCB to help with validating the communication bus as well as troubleshooting the design? In particu...
First clarify where this leakage current will be flowing. You seem to think that some parts of the solar panel will generate a small current thru the rebar into the ground, but where is the closed...
The magnetic field will always be strongest in the middle of the solenoid. It will be slightly less at the ends of the solenoid and, it will be a lower value on the outside of the coil half way bet...
If you're referring to this Wikipedia page then the topology has a negative output. In that case, the problem as you have it stated in the OP, is misleading: it should be Vo=-20. With that, extract...
That fourth connection is the bulk/body/substrate connection: - Image from here. On a normal 3 terminal MOSFET the "body" is connected to the source. On your device, the 3 n-channel MOSFETs shar...
Is the Thevenin's Theorem being applied incorrectly for the circuit ? It's being applied inaccurately. The final Thevenin voltage should be 2.782 volts (rather than your calculated value of 2....
No, a resistor divider is not appropriate, at least not if you want to get all the information from the STAT pin. In addition, that chart in the datasheet is incomplete at best, or downright misle...
