TODO:
- use a threshold
- set a tag when threshold exceeded
- feed in a noise source (average it?)
- tag blocker
- block to read tag, then change the output
- make a picture associating tags with samples
The previous tutorial, Python Block Message Passing demonstrates how to send and receive messages using the Embedded Python Block. The next tutorial, Low Pass Filter Example, demonstrates how to use filtering blocks in GNU Radio.
Tags Overview
Tags are a way to convey information alongside digitized RF samples in a time-synchronous fashion. Where messages convey information in an asynchronous fashion with no clock-based time guarantee, tags are information which are associated with specific RF samples. Tags ride alongside digitized RF samples in data streams and vectors, including Complex Float 32, Float 32, Byte' and all of the formats.
