Re: QT GUI Time Sink graph refresh rate

[Marcin Puchlik]

Hi Marcus,

Thanks for your answer. Please, check out this flowgraph.

Shouldn't the Time Sink update its graph content every second in this configuration?

Hi Marcin,

only if there's no other component that limits the speed of processing. For example, if
the samples come from an SDR, than that has a sampling rate, so there's only so many
samples per second that can reach your sink.

That only happens when the number of samples reaching the sink isn't sufficient to get one
full vector of samples per update period.

Best regards,
Marcus
