// The level of detail parameter determines which submodules of

// <table border="1">
//   <tr>  <th>Level (domain)</th>  <th>Submodules</th>                                                             </tr>
//   <tr>  <td>PACKET</td>          <td>-</td>                                                                      </tr>
//   <tr>  <td>BIT</td>             <td>signal encoder, data encoder</td>                                           </tr>
//   <tr>  <td>SYMBOL</td>          <td>signal modulator, data modulator + bit level modules</td>                   </tr>
//   <tr>  <td>SAMPLE</td>          <td>pulse shaper + bit, symbol level modules + (digital/analog converter)</td>  </tr>
// </table>
//
// Important: We have no default module implementation for sample level
// features.
//
// Note that if a digital/analog converter is provided for the
// transmitter, then it will be only used at the sample level. Otherwise,
// since analog representation is obligatory, a simplified, built-in
// (scalar) analog model is used at all levels.
//
// Note that in non-compliant mode, whatever the level of detail is,
// you must always set all submodules. If the current level of detail
// does not demand a specific submodule, it is necessary and sufficient
// to implement those methods of that submodule which provide metadata
// about its settings.
//
// For example, if the level of detail is bit level, you don't have to
// implement a complete modulator. It is enough to implement a dummy
// modulator that can give information about its subcarrier modulation
// (e.g. BPSK).
