Abstract:

The signals, for example, communication, radar, electrocardiogram, etc., are obtained using discrete time methods. Recently, level-crossing-based continuous time-digital signal processing (CT-DSP) methods provided many advantages like lower signal-to-noise ratio, no aliasing, lower processing need, and so on. There are not many effective methods for obtaining continuous signals from discrete nonuniform time measurements. This work applies the Lagrangian interpolation method to this problem and shows that it leads to a good reconstruction of CT-DSP signals.
