A source coupled differential complementary Colpitts oscillator is described, which enables a differential oscillation and also can improve phase noise performance by source-coupling a complementary Colpitts oscillator using an inductor. A linking device links the housing elements in such a way that they are movable in relation to each other, the first side facing the second side in at least one first state. Compression information is then associated with the compression data transformation used to generate data object C, and a threshold value T is calculated at least partly from the length of compression information I.
