I want to represent a .wav file(which is already recorded) in time domain graphically

[celia]

hi,

I want to read .wav file (I used read wav ....vi to read but don't know to represent that in  time domain graphically)

and represent in time domain and later in frequency domain and obtain its power spectrum.

Pls someone guide me to get the time domain representation of .wav file data.

Thanks in advance,

Celia

Thanks i got what i wanted.

Now I have to modulate it (using PSK).

help me.

How to use digital waveform graph. I'm seeing multiple plots.

You'll have to show us some code. I'm using 7.0 format.

To use MT modulate PSK.vi i need bit stream how to convert the data i obtained into bitstream

Suggest me.

I've sent the code.

There are no VIs to convert an analog signal or a wav file to a bit stream for PSK modulation. You would have to do this conversion. Is there a reason you want to use PSK instead of PM?

yes, I want to do Digital Modulation. PSK being the better option.
