| 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 14 bit signed little endian number. I value | |
| 20 | comes first and Q value after that. 14 bit value is stored in 16 bit | |
| 21 | space with unused high bits padded with 0. | |
