How does the receiver understand the end bits? It doesn't. The purpose of stop bits (what you seem to be calling "end bits") is to leave a guaranteed gap before the next start bit. The leading e...
It's not clear that the problem is. It seems you want to interface to this "digital air pressure regulator" via two 4-20 mA current loops. For reading the output, it should be as simple as a 24 V...
I think the biggest reason is that it may be difficult to control your function generator with an output of only 5 mV. Some function generators have different output ranges that are switched, then...
I was the one who started that list Elsewhere. I thought the same as you, that a few common abbreviations would be good to have in a single place. However, it quickly turned into a mess. After o...
It seems you have ground loops, and possibly having multiple ground connections shorting out your signals. Your hand-sketched diagram is a good start, but you need to show all the ground connectio...
You are asking how to analyze this circuit: Forget about what you think it should be called. Before attempting to model specific aspects, first try to understand the circuit. The opamp provide...
A resistor is not a good model for a saturated BJT. According to your graphs it is, but those are simplified. There isn't really a single slope for all base currents as your graph shows. Even if...
I have decided to try design a band-pass filter with a cut-off frequency of 10kHz and bandwidth of 2 Hz. It's "10 kHz", not "10kHz". There needs to be a space between the number and the unit. ...
Your question doesn't make a lot of sense. for a sinusoidal input signal s = jω the pole exists at the resonant frequency ωr. Actually the pole exists regardless of what the input signal is. The...
There are a number of misconceptions here. bode plot db/Hz First, it's "dB", not "db". Second that's not a Bode plot. Those are dB/Log(Hz). In other words, a certain frequency ratio results in...
We have such low volume as it is, that I wouldn't want to see another category added at this time. It would only emphasize how little traffic there is. Let's not make the same mistake that Photog...
This can be OK if you consider and address the consequences carefully. It's something I would only do as a last resort. Usually I try to make sure the hole itself is outside the outline of the pa...
I agree that "208VAC" and "230VAC" are too specific to be useful. I tried to edit the post to remove them. There is apparently a bug in the system. While I removed both tags from the post, one o...
It sounds like you are doing the measurements right. However, I expect the problem is in the space around the antenna. At 434 MHz, the wavelength is 690 mm or 27 inches. Everything out to about ...
I think "dangerous" is pretty clear. It's when doing as recommended can cause significant damage to property or health. For example, recommending to a hobbyist to make a direct line-connected cap...
I don't think there is a formal term that means exactly what you describe. Switching transients generally means short term glitches that might cause noise, usually resulting from power being switc...
That's a marketing blurb. Look at the real datasheet. I just checked a polyfuse datasheet, and see that there is usually only about a 2.5 to 3.0 ratio of trip current to hold current. That shoul...
The circuit you show doesn't make any sense: Start by examining the steady state condition. In steady state, C1 is effectively an open, so you ignore it. R4 keeps Q1 on. That means the collec...
For reference, here is your circuit properly drawn with component designators: The question is what happens when the inductor current starts at 0, then the switch is closed. The first observati...
with just one mode Others have already explained that "discrete" means a finite set of values, not just two. This is to point out that having just one "mode" (it seems you mean symbol) doesn't ma...
I dont understand how to make a logic circuit which does that job:check if the divisors is greater and equal or less than the most left digits of the divident So think about it. Break it down int...
Take a look at the circuit and try to see what function it will perform on the input signals to yield the output signal. For simplicity, let's consider the diode ideal, R1 and R2 the same, and R3 ...
I just happened to re-read this question, and I now think I see better what Microchip was trying to say here: On closer examination, I think this is actually correct but badly worded. I believe...
You need to be more careful. First, you should have been able to see for yourself that the first equation isn't written right. I'll assume the whole "-0.5t" is the exponent of e. You were too sl...
At first glance, R22, C22, and C23 look like a compensation network around the TL431. However, this doesn't make much sense because the TL431 is being run open loop. Rfbt and Rfbb divide down the...
