Re: QT chooser and QT range do not cooperate with each other

[Christophe Seguinot]

I would have implement this differently:

• First solution combine To filters taps in one filter such as
• final_taps=rrc_taps*(pulse-1)+rect*pulse
• with pulse =0 or 1 (obtainde with a QT GUI Chooser)
  
• BUT filters must have the same number of coefficients
• 2nd: use QT Gui selector as in this flowgraph. (it can be extended to multiple filters easily)

P.S. my flowgraph is for GR 3.8 /3.9

Hi all,

I have a flowgraph with QT chooser choosing between rect pulse and rrc pulse.

I also have a QT range where I want to control the rolloff factor of the rrc pulse when chosen.

However, in the flowgrpah it seems that once the rrc is chosen I cannot change its roloff factor dynamically from the QT range.

I have tried it in both 3.7 and 3.8 and I get the same result.

Is this a bug?

Is there a more appropriate way of achieving this result?

thanks

Achilleas
