Resetting d_delta in custom Delay block causes a spike in time sink

2021-02-01 Thread Ethan C
Hello, I am trying to create an OOT block similar to Delay except that if it does not receive any data for 10ms, it will reset the delay (set d_delta to the same # of samples as the initial delay) so that the next portion of received data will have a delay before it, as seen here

Hi Crostophe, thank you for this wonderful tutorial. You may want to use the more standard terms: "pre-envelope" m_+(t) = m(t) + j \hat{m}(t) (ie, the signal you currently denote as \tilde{m}(t)) "complex-envelope", \tilde{m}(t) (for the signal you currently denote as m^{bb}(t) ) thank you

Hi Two months ago we had long discussions about why GNURadio was using complex signal, and what really is such a signal.  We talked about 'spinning dancer' 'sampling the data twice', and using "dogs as local oscillators". It was obvious that we need
