Re: Selector Block GNU radio

Hello!
In order to grant good performance, using selector is not a good choice.
The best way to achieve reconfiguration is to change modulator (as well as sample rate) at runtime dynamically handling the flowgraph (lock/unlock and stop/start).
Have a look to https://wiki.gnuradio.org/index.php/Handling_Flowgraphs.

Hello,

GNU Radio version 3.10

My requirement is to switch between multiple waveforms. For this purpose, I think I should use the Selector Block. However, my issue is that each waveform chain has a different sampling rate: Waveform1 has 1 MSPS and Waveform2 has 2 MSPS, for example. 

Can the Selector Block support inputs with different sampling rates like Waveform1, Waveform2, etc.? 

I plan to switch the runtime sampling rate of the Source block connected to the output of Selector Block. 

If this setup is not the right approach, please suggest how to achieve this.
