Hi Kevin,

the problem arises since my blocks detect signals in the spectrum and estimate their bandwidth. Then, each signal gets filtered and decimated to the needed sample rate according to Nyquist-Shannon. This sample rate is well defined, but only known during runtime.

That sounds reasonable, but you aren't going to be continuously changing the sample rate estimate, I assume, so you should be able to have the estimator report its estimate to your application code (the code that created the flowgraph in the first place) which then reconfigures or replaces all of the downstream sample-rate blocks.
