Re: [Discuss-gnuradio] Switching between various signal generators

[Chad Spooner]

Blake:

Thanks so much for your tip on mux and selector. I had hit on "Stream Mux" this morning, but hadn't seen 

"Selector". Stream Mux is working for my first task. The second task is harder, and as you say, I'll probably have

to get into the code.

The easiest way I see of doing this, is running all of your signal generators into a stream mux or selector. And then select the desired signal to pass through.

See https://lists.gnu.org/archive/html/discuss-gnuradio/2014-05/msg00631.html

As per your requirements, you may be able to cobble something together with blocks with some clever thresholding. But it is likely easier to use python to change your mux/selector.

All:

(Thanks to Marcus and Cinaed for responses to my previous question on GLFSR.)

I have a set of working signal generators built in GRC 3.7.9. I want to do two related things with them.

I'm hoping to do these things within GRC, but of course if I have to do lower-level programming I will.

1. Visit each signal generator in turn on a specific periodic time schedule. Say, after starting the flowgraph, switch to another signal generator every T seconds, where T is something like 1-10 seconds. I want to be able to specify the particular sequence of generators, but the schedule for switching between them is periodic.

2. Visit specific signal generator on an arbitrary schedule. At time t=0, use Generator 0, at time t=T1, use Generator 1, at time t=T2, use Generator 2, etc.

It is preferable that there is no gap between the transmissions of the generators. 

I would much appreciate any tips on how to accomplish these tasks.

Thanks,

Chad
