sampling analog signal- Sample and Hold!

[traceabc]

Hi,

I just started learning labVIEW so I am very new to labVIEW environment( there is always a first time for everything).. I just learned the basics ..Now I am trying to implement a simple basic Sample and Hold but unfortunately no idea (and no one to guide me) as to where to start from or how to do it..I know for sure an analoge signal generator(sine wave) will be required but where to go from here 😞 

Can you please help me? any algorithm, hint, reference vi..any type of guide will be appreciated !! I have the concept but not the idea on implementation!! 

Any help is appreciated..

Thanks

**SORRY for the double post..had no idea as first one was showing error and not posting**

Do you have any daq card on your Labview PC. That would be helpfull to know

Hi,

No I don't ..I am just looking for very basic implementation ...hints to start and how to do will be helpful

i have to implement sample and hold in labview and as i am new to labview thats y have not enough knwldge how to do!!!

kindly give me explaned and effective answer.An example will be more helpful and appreciated

thanx

Perhaps an explained and detailed question? Sample and hold of what? LabVIEW is a programming language and not an electonic circuit simulator. Are you perhaps looking for Multisim?

sample abd hold of sine wave....as normally we do in signals processing or signals and system!!!

simply taking a sine wave as an input and apply sample and hold or we can say that to detect its peaks to take it as digital aor discrete shape.

If this is a Labview school assignment. Try using case and a shift-register

thanx 4 guidance....let me try

Hi,

Okay here is what I am trying to do..just the basics..Sampling is a stage in ADC ..i am just trying to reproduce this behaviour..taking an audio input (or any input ) in the analogue continous form..I thought of multiplying it with an impulse train (at a particular sampling frequency) so as to generate the samples at the each sampling interval..I was (I think) able to generate ann impulse train but once it is multiplied with the original signal, it gives nothing at the output (should be a sampled signal)

I have labview 2010!! so I am attaching both vi and screenshot!

Take a look..any help/ideas/changes are appreciated!!

thanks

I do not understand your VI. And what values do you use for the controls. They have all zero as defualt value.
