[Discuss-gnuradio] inband signaling and m-blocks

[Achilleas Anastasopoulos]

Hi,

I have a couple of basic questions regarding USRP inband signaling and 
m-blocks.

1) Should these two be used together, or are they separate, eg, can i 
use inband signaling with standard blocks?

2) There is a brief description of inband signling in the trank; is 
there a simple example that i can look up to see how it works in practice.


I have in mind something really simple: I want to build a transmitter 
that transmits a sinusoid or nothing in PRECICELY specified time 
intervals; thus my interest in inband signaling.
When I understand how to do that I want to build a frequency hopping 
transmitter/receiver...


Thanks
