pc123 optocoupler datasheet
Thanks for your great responces...
I intended to use the opto isolator at the input of my PCB directly after the connection of patient..
My PCB use an ordinary 12 V AC/DC adaptor, so there's a danger for patient from the 50 hz interference.
I thought that the best...
optocoupler tutorial
I'm designing an ECG cuircuit.
I need to use Opto Coupler to isolate the human body from the electronic circuit and the power supply.
I've got 4N35 opto-coupler. I've the datasheet but still don't know how to connect the 4N35.
Anyone can help...?
Thanks alot.
Hi all,
I know nothing about microcontrollers or PIC's.
I just want an ADC to apply an analog signal to pc and process it with matlab.
I think Analog/Digital conversion by microcontrollers are better and cheaper, is that right?
I want anyone to help me choosing one to satisfy my needs.
What...
matlab comunicação digital
I have a specific question, hope i can explain what i want exactly.
I've designed a GUI as a small program.
My problem is how to terminate the program or to close it.
I made a pushbutton and changed its string to CLOSE.
I make the callback of this button as

9v bipolar 4.5v split
Thanks FVM,
So i may apply this circuit as it is except for adding a 10 ohm resistor in the feedback path of each opamp,( i.e between pins 1,2 and pins 6,7).
Is that right?
Should this resisrtor have the same values with R3 & R4 or it's not important.
The last thing, what...
circuit to split a single power source into 2 dc
My circuit diagram is not ready right now. I don't have a soft copy of it.
I thougt that it's easy to explain the splitter circuit to me, which i may use or apply for any general circuit not a specific one.
Just like the circuit i've found and...
bipolar power supply schematic +4.5 -4.5
I've found this circuit.
**broken link removed**
I wanted to share it with others.
what's ur opinion about it. Is it good.
And what about 1458? Is it LM1458.
It's a dual opamp. Is it noisy or good?
Can i use LM358 instead?
Will this circuit work well...
lm358 virtual ground
Hello,
I want to design a simple circuit to generate +4.5 v and -4.5v from a single 9 volt.
I'm designing a small circuit, and instead of building my own power supply i decide to buy a regular 9 volt dc adapter as a power supply.
I want not to use batteries to guarantee a...
matlab psk with broadband interference
can anyone help me.
I wanna matlab code for calculating the herat rate or a heart beat for an ecg monitor.
It's the last step in my project.
I've made some code but it's not so accurate.
Anyone can help.
