is there any other method instead of matlab like sound recording port or something. or of there is any other way please help me . tell me the easiiset possible way to connect.. thanku in advance.. please plzz plzz helpp meee sirr
 

Hi,

Convert ur Analog output to Digital and use LPT port
here is a sample code in VB 6, Its an Oscop program to show input signals on the PC.
I hope it helps u... :D

no ones helping me outt :( :( :( :(.. nt fairrr thts my last year project..plz help ive gt vry less daysss plzz helpp meee guyzzz :(
 

you can send this through microphone port to computer. Matlab can access this port

Added after 51 seconds:

Through microphone port u can send analog signal
 

1. use ADC ICs to convert Analog to Digital using TTL. search 'how to convert analog to digital circuit'

2. dear rongo024 said use mic port. you can try it.

3. or you can use a microcontroller to convert ur analog to digital

the best ways, and easy ways, are 1 and 2

that vb source code, is easy to use
 

guyzz
thank you for reply dis is quite helpfull.. but i was thinkin if i connect from sound port and den how can i access it on matlab coz den i hav to generate the heart beat pulse on matlab. how can this be done?
