Thanks a lot for all the information you have provided. I will start reading about directsound. thanks again.

Thanks. But can you suggest a good method to capture signal through the sound card inputs that would allow me to analyze captured signal? I have read about some multimedia libraries available for C++, but most are seems to be just allowing to record data and save them to a file, or to play...

Thanks for the reply. The device that I have is a very simple one made by myself. Its picking up electric signals through electrodes and amplifying using an opamp. I thought of using the soundcard's inputs to connect the output of the amp to the pc. I found several multimedia libraries that...

How to read a signal through the sound card? I want to capture an amplified electric signal that emerge in the heart, and then to draw the ECG diagram. Can I use the soundcard's jacks for this purpose? if then, what is the best method to use to capture these signals using C++ on windows...

There is a text document with data separated by the "," sign. such as 58.5698, 75.2495, 57.1548... I want to createa vector called Y in MATLAB using these datas. there are 50 values. i opened the file with the fopen command. And then tried with the fgetl command. but when I use the...

following is an example question i found on a lecture slide. I need some explanation to understand it. http://img266.imageshack.us/img266/7062/thermal.png Uploaded with ImageShack.us In this example, Is it possible to get the thermal expansion coefficient from the data given in the...

young's modulus thanks, now i got an idea about how to do the calculation. to which units i should convert these into when calculating?

Hi.. I need a good explanation for the following question. an explanation with a small mathematical calculation to prove the answer would be highly helpful. A copper rod of cross-section 10 mm  10 mm is stretched along its axis, changing length from 1.000 m to 1.001 m. The deformation is...

I need to study about the variable pitch propeller and its mechanism of adjusting the angel of the blades. And also about the materials used to make propellers and their benefits.. can someone please help me to find sources such as images/videos about the variable pitch propeller? or...

I have to do a presentation on atomic theory and periodic table. What are the interesting points I can include to my presentation? Thanks in advance!

when an electron moves closer to the electric field source, does the potential energy get higher or lower? if it is being accelerated from the infinity, then at the infinity it should have the lowest kinetic energy? then when it is closer to the source of the field, it should have the...
