Elimination of the chirp of optical pulses through cascaded nonlinearities in periodically poled lithium niobate waveguides

, 2010
We propose and demonstrate a novel method for the elimination of arbitrary frequency chirp from short optical pulses. The technique is based on the combination of two cascaded second-order nonlinearities in two individual periodically poled lithium ...

ECG Artifacts Suppression Using the NLSRA-Based Cascaded Fixed Point Interference Canceller

, 2023
The newly proposed Normalized Leaky Sign Regressor Algorithm (NLSRA) is used in a cascaded fixed point interference canceller for ElectroCardioGram (ECG) artifacts suppression application. An upper bound for the NLSRA algorithm step size is also derived.
