| Signal Generator Script 1.0 |
| =============================================================================== |
| This script takes command line arguments to broadcast the sum of various signals |
| with differing strengths. The script takes in arguments by specifying a type of |
| signal to broadcast followed by the corresponding parameters for that signal. |
| This script requires the user to specify at least 1 signal in order to operate. |
| In order to broadcast from file, use the '-f' flag and specify the path to the |
| file as well as a factor which corresponds to a db-gain on the specific signal. |
| A general db-gain can also be specified by using the '-g' flag to amplify the |
| combined signal. |
| |
| Usage: signal_generator.py [options] |
| |
| To print usage info use "./signal_generator.py -h" option. |
| |
| Note: If you are playing from a file and are getting Underruns (U), try moving |
| the file to local storage. |
| |
| A set of useful recordings have been placed at "/google/data/rw/teams/gfiber/sdr/recordings" |
| that can be used for testing or other purposes. |
