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. | |
