Re: [Discuss-gnuradio] Difference between examples/ofdm/benchmark_tx.py and examples/ofdm/tx_ofdm.py

[Martin Braun]

You can basically ignore benchmark_tx.py, it's deprecated, will be
removed soon and uses old APIs.

However, in an nutshell, benchmark_tx.py is a transmitter application,
whereas tx_ofdm.grc is a GRC flowgraph that demonstrates the internals
of the OFDM transmitter.

Cheers,
Martin
