30
*
31
* Abstract class that establishes symbol timing and synchronizes
32
* with data segment boundaries.
33
*
34
* Takes a single stream of floats as the input and
35
* produces two streams as output. The first stream is the data samples
36
* and is of type float. The second stream is the tags, and is of type syminfo.
37
*
38
* The current GNU Radio interface doesn't currently support different
39
* types on the input ports (or output ports for that matter), but
40
* since they are the same size, it works.
