## Applications ## Applications
The Stabilizer firmware offeres a library of hardware and software functionality This firmware offers a library of hardware and software functionality targeting the use of the Stabilizer hardware in various digital signal processing applications commonly occurring in Quantum Technology applications.
exposing input/output, timing, and digital signal processing features. It provides abstractions over the fast analog inputs and outputs, time stamping, Pounder DDS interfaces and a collection of tailored and optimized digital signal processing algorithms (IIR, FIR, Lockin, PLL, reciprocal PLL, Unwrapper, Lowpass, Cosine-Sine, Atan2).
An application can compose and configure these hardware and software components An application can compose and configure these hardware and software components to implement different use cases.
