Re: [Discuss-gnuradio] Delay block controlled by input

I am having problems with the clock.
I need to track the real time of the signal. I have tried to get it with a sample counter and a throttle (to maintain the rate), but it doesn't work. The clock is faster or slower than the current signal time.

Any idea? ;)

Ok. My problem with this is that we're trying to get away from using streaming data ports for control like this. Changing the state of a block should be left to stream tags or messages.

For your application, it might make sense if each data input to the block matches to a very quickly-changing delay difference. In that case, though, I would suggest that you keep an OOT module with your own implementation of the delay block that does this for you.
