Hi Henry, GNU Radio, as far as I understand, does not have a concept of time. It will try to process samples as quickly as they are available. If your input sample is arriving every 50mS then a sample should be produced by your block shortly after the 50mS arrival mark.
What do you mean, the output value should stay there? The output value is shipped off to some other block that connects to yours. --Colby On Tue, Jun 14, 2011 at 10:35 PM, Henry Matt <[email protected]> wrote: > Hi, > > I have made a custom block derived from gr_block which has two inputs. > First input comes at a sampling rate of 20 samples/sec while the other input > comes from the gr_noise_source block.
