FM Transmitter using USRP

[Marwanjk]

Hi everyone,
i'm trying to build a Fm transmitter using the sound input.
I can't make the correct data conversion from the data acquired from "sound read module" to the FM modulator.
I use the "FM Radio Demodulation" as example but I can't reach to modulate the data with the FM modulator.
In the image you can see what i've been doing.

Regards

Hey Marwanjk,

The Sound Input Read VI data is an array of waveform data, where each element in the array is the data from a different channel. If you have a 1 channel system, you will have a 1D 1 element array of waveform data.  If you have a 2 channel system with left and right audio, you will have a 1D 2 element array of waveform data, where the elements will coorsepond to the left and right data. 

The FM Modulate VI is expected waveform data, not in array form.  If you extract the elements from the array and feed them into the modulation node, you should be good to go.  Check out my attached image.

sir please send me MT fm modulate.vi

sir please send me sub vi ' mt fm modulate.vi' on my mail id 'manjinder99990@gmail.com'

Hello,

The MT Modulate FM VI can be found in LabVIEW if the NI LabVIEW Modulation Toolkit is installed, and can also be found in LabVIEW Communications if the RF drivers are installed.

Also - we just released USRP support for LabVIEW NXG 2.1. If you want to do FM, just download LabVIEW NXG 2.1 and the NI USRP driver that supports NXG 2.1.

LabVIEW NXG 2.1 (go to Start Free Trial): http://www.ni.com/en-us/shop/labview/labview-nxg.html

NI USRP: http://www.ni.com/download/ni-usrp-18.3/7823/en/

You shouldn't need the whole of LabVIEW Communications, which installs Linux RT and FPGA add-ons to LabVIEW NXG.
