For maximum performance, the formats "Compatible" or "IQPair" should be used. Fur-
thermore, for large amounts of data, the data should be in binary format to improve
performance.
In binary format, the number of I- and Q-data can be calculated as follows:
For the format "QBLock", the offset of Q-data in the output buffer can be calculated as
follows:
with "LengthIndicatorDigits" being the number of digits of the length indicator including
the #. In the example above (#41024…), this results in a value of 6 for "LengthIndica-
torDigits" and the offset for the Q-data results in 512 + 6 = 518.
