ecg simulator circuit

I want to know how to sample the ECG signal and how to use the microcontroller in desining a circuit that simulate the ECG wave forms , plz it is urgent , thanx alot.

Automotive inition systems look some what simmular!

Grab a Flash Coil from a Camera flash and use The MICRO to trigger it

Silly method, I use it sometimes
Graphs of ECG you can find easily in the Internet
You can use audio editor like Gold Wave
Start new file of few seconds and 2k-sample rate
Generate low frequency square wave
Cut the negative part of the square wave
From Volume – Shape menu, shape the positive part of the square wave similar to one ECG wave cycle
To smooth the curve use low pass filter
Save the file as type - text integer mono
Now you have text file with numbers for lookup table for the microcontroller
To play it you need controller with DAC or use external DAC or if poor quality is OK use 8 resistors R,2R,4R.. to build primitive DAC


Just for basic knowledge – the final ECG graph you usually see is superposition of several signals form 3 up to 12 electrodes dependent on the ECG monitor quality

thank you , but i wanna now how to write the programe , and how to implement it in a circuit in detail plz , its my project , and i'm trying to do my best.

thanks for all.

emad.

Why you need simulator, it can be generated by the simple circuitry.
Search the article on the elector-electronics magazine.
I know that it is there but I right now don’t know the exact issue no , month
It contains 2-3 digital ics such as 4017 etc.

Also you can test it on any simple simulator software.
If farther, I get it I will send it to this as attachment.

man

your doing nothing

you expect us to do all

YOUR DONKEY WORK


go invent your own technique

dont expect others to do your easy work

its your project and so very easy


get on with it and dont be so lame
:evil:
