Re: [Discuss-gnuradio] varying the bandwidth of a signal in GRC

[sreeraj r]

Hi Jason,

Please go through this,

http://gnuradio.org/redmine/projects/gnuradio/wiki/TutorialsCoreConcepts#Sampling-rates

Try

1. Varying USRP sample rate and observe the output using  FFT sink

2. In the flowgraph use an interpolator (rational resampler) just before your USRP sink, vary the interpolation factor and check the output.

Things will be more clear then.

Thanks

Sreeraj

Thnx Marcus..u mean that if i change the sample rate of USRP sink
block in the properties dialog box then the bandwidth will be equal to
the changed sample rate??
