Overview
FM Signal acquisition and demodulation.
Description
Frequency modulation is very used to transmit data by using a carrier frequency that vary the frequency of the data being sent. This modulation scheme is used specially in radio communications. After the transmitter send the information, a receiver device will obtain the information and needs to pass the data through the inverse process called FM Demodulation.
This example is focused to understand the configuration that we need to set on an USRP in order to demodulate a FM signal.
Requirements
1. LabVIEW 2015 (or compatible)
2. NI USRP 15.0
Any compatible USRP device.
Steps to Implement or Execute Code
1. Open the "FM Demodulation LabVIEW 2015 - NI Verified.vi"
2. Configure the properties of the carrier frequency.
3. Run the VI
4. Observe the behavior on the different waveforms displayed.

Hi dityA9762571418,

Hope this helps,

dear sir,
i been implementing FM transmitter using USRP 2920. my VI is running continously but no output . here i attach my soundfile along with vi program
kindly tell me where the error is ?
