It's a very simple circuit, but I wouldn't be that quiet. Transient periods will generate huge losses between both transistors of each driver.
The square wave goes from 0 to 12V (aprox.) in a very short period of time, when the signal will take every voltage value between these given two...
Not enough information, you should be more specific and more people will understand your question, so higher chances of being helped.
I assume you want to generate a 120V 60Hz sine wave signal. How much power are you planning to use? I think TL494 won't fit in your application, as its main use...
Hello,
I use KiCAD and I have designed several medium complexity PCBs. The most annoying part when designing the PCB layout is the size and the position of connectors, mounting holes and pots/switches/LEDs, etc. when you haven't a defined enclosure. It's obvious but I had to mention it, because...
Thank you for your responses.
Finally I got an Intel I5 7200U. Running with a sataIII SSD disk and Windows 10 64 bit, I have a really good experience, very fast response and 20 seconds to boot.
When I use VM for Linux the RAM fills up to nearly 70%, glad I bought the 8GB version PC. It's been...
So, do you think it's worth to buy a laptop with AMD and dedicated graphics card? It's in the same price range as the one I was talking about, but again, I mean, these laptops are designed for gaming, will they work fine for office and engineering tasks?
And another one: Do you think changing...
yeah, I was actually thinking about moving to Linux, but are most programs compatible? I know that maybe 10 years ago most programs would have trouble in Linux, if they were even developed for it, how's the scenario nowadays? I know all the electronics programs I use are available in Linux and...
Thank you for your answers.
So intel are more reliable in long terms of time, I understand. AMD is often more frequently seen in gamer PCs so they must be designed for that use; graphics the most, they actually have more internal GPU speed.
Another question: Do you recommend me to install...
Hello everyone.
I have been searching in several PC/gaming forums and I didn't get my answer, and this forum is the most addecuate to, so: AMD or Intel?
I want to buy a new laptop for working in my engineering projects, I work mostly in electronics (Simulations with LTSpice, Matlab/octave, PCB...
Re: Hum with single-to-split power supply for equalizer.
Well, actually it wasn't so necessary, but as I didn't have time to test the 2 resistor virtual ground, I just put the transistors to assure low impedance, which I think is good to avoid noise in the supply. But it works pretty well, and...
Re: Hum with single-to-split power supply for equalizer.
Well, finally I got some time with my amplifier close to the oscilloscope so I said "hey it's a good time to measure its signals and supply" so I did.
I found out the problem: First, the output signal (from equalizer) was a VCC/2 with...
Exactly. I would recommend 1K and 330nF. It allows fast spikes to go through the supply to the load, but will prevent long-term overvoltages (for example, using a wrong transformer/supply). What's the MOS ON resistance? Maybe with its value and a capacitor, you can calculate a filter these...
Oh yes, I read wrong. When someone passes through the barrier, it will put 0V as output. You could use a P-MOS as Klaus says.
Another thing to keep in mind: If a person pass trough it, the signal will be 0V only when the light barrier is blocked, which is less than half a second at normal...
Hi Alex,
First of all, it's a good practice (and pretty necessary) to have a topology standard to draw schematics circuits, and it does exist:
-Higher potentials up, lower, down. Just like the water falls, from top to bottom. You put all GND in the upper part of each circuit section, it should...
Hi mpiepen,
I think the circuit you've made is not correct, first of all the transistors polarity, the upper one should be NPN and... BJT? I don't think you have a 4 terminals BJT transistor.
How does the light barrier work? When there's an object between emitter and receiver it outputs...
