overshoots in the output.
\item \texttt{digital\_gain=0.8} reduces the output sample deviation, to
reduce compression in the USRP.
- \item \texttt{firfilter enabled=1} enables an additional FIR filter to
- improve the spectrum mask.
+ \item \texttt{firfilter enabled=0} can be set to 1 to enable an additional
+ FIR filter to improve the spectrum mask. This filter needs a file
+ containing the filter taps, which can be generated using
+ \texttt{ODR-DabMux/doc/fir-filter/generate-filter.py}. An example taps
+ file is also available in this folder.
\item \texttt{master\_clock\_rate=32768000} sets the USRP internal clock to
a multiple of $2048000$, which is required if we want to use the native
DAB sample rate.
