| 14 | Description | |
| 15 | =========== | |
| 16 | ||
| 17 | This format contains sequence of complex number samples. Each complex | |
| 18 | number consist two parts, called In-phase and Quadrature (IQ). Both I | |
| 19 | and Q are represented as a 16 bit unsigned little endian number. I value | |
| 20 | comes first and Q value after that. | |
