Sorry, but I have to challenge your premises when you say that most numbers are "round numbers" and that could be a reason for choosing some value. You compare those values by the number of decima...
This discussion was prompted by answers to this question. While the answers are good (basically, when designing for the medical field, either be or hire someone knowledgeable about the specific re...
Assume that I have some generic antenna connector, followed by a pi-filter/50ohm impedance matching components, then a DC blocking cap (as per the RF switch recommendations) and then a RF switch fo...
I have been observing these little cases hanging to the wires from a long time. They are almost everywhere here in India, but I was unable to find out what they are. I am not sure whether they are...
I don't think there is a simple way to inherently limit the current to 10 A. The best approach seems to me to add a low side current sensor between the bottom of the H bridge and ground. The main...
Around the 19 min mark in the video (approximately, found with hovering the cursor over the timeline) you'll see that different capacitors have different values of both capacitances and parasitics,...
I am calculating the base current of transistor Q1. To simplify the circuit equations, I applied the Thévenin's theorem twice and converted V1, R1 and R2 into Vth and Rth, as shown in the image. ...
I see that Monica answered your question directly. However, there is another point to keep in mind. Comments are not for content. That was supposedly the case at SE too, but was poorly enforced....
If all four channels are really connected to the same signal in the pictures you show, then there is indeed some skew between pairs of channels. Try swapping probes to see if the lag goes with the...
My goal is to make an RC car, and I have a couple of questions regarding driving the brushed DC motor. Schematic for half of my H-bridge looks like this for now (it will be identical on the other s...
Yes, you seem to understand the concept. From the case to the ambient air, there will be 1.3°C per watt across the pad, and another 2.0°C per watt across the heatsink. In total, there will be 3.3...
Every time I visit Codicact I miss the comment voting feature. There is no way to know if some comment is rubbish or a gem because the opinions of others are hidden from future visitors. I wish t...
You should not be relying on the internal circuitry of whatever senses the 4-20 mA current. Note that the two implementations you show both use current sense resistors. The only difference is the...
Homework problem A MOSFET has a power dissipation of $P_{d} = 10\text{W}$. The MOSFET is mounted on a heatsink. There is an isolation pad between the MOSFET case and the heatsink. We are given t...
I posted a post containing C code in the Papers category here, using the ```c formatting which works elsewhere on Codidact. The code does not get formatted with color coding, though it gets fixed ...
Code highlighting, like Mathjax, incurs a small penalty on page rendering, so we don't turn it on by default. The question hadn't come up before on EE, so it was off. I've just turned it on.
The usual culprits would rather be the ground clip itself or accidentally shorting something with it, more so than ESD. And if something has actually broken on the scope, I'd suspect the probe to b...
In general, the on/off delay is how long it takes from changing the input until the output starts to do something. The rise/fall time is how long it takes to do the something, once it starts doing...
The Murata part you have chosen as a replacement is unsuitable. Its only application is to cheaply replace crystals in oscillators and, as such, it will have a profoundly tight bandwidth (maybe les...
#1 before anything else is to do your homework. The Nordic semi web site says: "nRF24 Series Not recommended for new designs". That means forget about using this part! They are phasing it out of pr...
I have a non-invasive current sense transformer (SCT-013-030) which according to its datasheet it is voltage output type. I want to harvest energy and supply a wireless sensor that consumes 5-6 uA...
I am planning to use the LM318 operational amplifier to generate a PWM signal and I need to know how to calculate the rise/fall time. LM318/LM218/LM118 datasheet -The slew rate is 70 V/µs maximum...
According to the datasheet that Andy linked to, the chip can be configured for 0 dBm output. With the proper antenna, that is probably good enough for 20 m, but you'll have to test it yourself to ...
The data sheet gives a perfectly good example of using the nRF24L01 without an external PA. It has an internal PA capable of driving an antenna <-- just look at the design example on page 63 wit...
Rise and falls times are limited by the maximum slew rate the opamp can produce. This is something you look up in the datasheet. Note that the slew rate might be dependent on supply voltage and p...
