Terminology Translation

GNU Radio

Being more of an implementer than a mathematical theorist, I’m
having trouble “translating” the “language” spoken by our
local Matlab/Simulink boffins.

What’s the proper way to implement an “Integrate and Dump”
operation in GnuRadio. I’ve come across several mutually
contradictory suggestions.

The most straightforward way is to use a normal FIR filter with all taps
set to 1. This is not terribly efficient, but will get you what you
want.

The gr::blocks::integrate_xx blocks perform what you need, in that they
accumulate successive samples up to ‘decim’, then output the result, and
clear the accumulator.
