i have done yet NO ANY real tests confirming the feature nor do i know too much about this -- just that the Spice's...
Hi,I have a problem with ab class amplifier for my school project.I know a little bit circuit components which has a specification in that circuit but I dont know how to make theoretical analiysis. Which formulas I need first for this circuit

I accidentally touched the motherboard in my PC (pre-built lenovo Thinkstation, working perfectly before) with a measure and it immediately turned off. Now when I try to turn it on not all fans start spinning(the one on the cpu does) and the monitor doesn't show anything. There is no burnt...
I'm looking to build a theremin with a built in analogue reverb and possibly EQ (still unsure about whether that is of any use for a theremin) for my Dissertation at University (audio course). I've never built anything electronic before however I studied electronics previously at college so I do...
Q. Design a comparator circuit for comparing two words, each of 5 bits of input using 1 bit block ? [ Logic Diagram needed ] :)
The load current is independent from supply voltage and the load resistance
Hello,
So I'm currently trying to read an analog sensor of one of the expansion modules. The problem is that it's not reading it at all. When i try to read the sensor using the plc (cos it has analog inputs) there's no problem at all. so, the reason that i'm reading the sensor with the...
Dear Experts,
I am a new user. I need to develop a differential clock generator with Ring oscillator as a switch for S/H circuit of a 50nm pipeline ADC. I have already designed my OpAmp. My input voltage is 1V. frequency 100MHz. To make a S/H circuit i have been asked to design a switch. To...
I don't know where this first entry will appear on the forum, so this should be brief and general. I know very little about electronics. My intent is to use the educational tools on this site to lean how to design and make ac to dc converters, inverters, battery chargers, and how to manage...
I a new user to PROTEUS , but I am quit surprise to see the performance
for example you project can run even if
there is no Vcc or ground
signal such as EA is high or low
reset is connected or not
crystal is connected or not
Is there any setting that restrcit PROTEUS to simulate under real...
Hello everybody I'm trying to diagnose a problem with a panasonic mini bookshelf stereo. The CD player skips on all tracks from beginning to end but if you tilt the entire stereo it's fine?????. So far I replaced the laser pickup but still skips. I work as a TV repairman and so far I repaired...
In my engineering exploration project in 1st sem, I need to design a self oscillating toy horse for 3-5 yrs old which can bear their load and has variations of speed controlled by arduino uno.Can anyone suggest how to go about it?
:eek::eek::eek:PEOPLE, I REALLY NEED HELP, because the competition is basically in 2 days, and i dont have my venicle built yet!!
Also, will the fan i chose be able to lift itself??o_O
And please don't use "professional" words, because im only in middle school, and I didnt learn that much of...
I am trying to repair the Controller Board for a Merlin/Chamberlain Prolift M230T garage door opener. It intermittently switches the courtesy light relay on and off, eventually blowing the bulb. I cannot find any circuit details for it. Can anyone help?
