Sisendsignaalist

Sisendsignaalist is a term used in Estonian-language technical contexts to refer to the input signal or the data derived from it that is used by a system, model, or analysis. It can denote either the abstract concept of an input signal or a concrete dataset comprising samples of that signal.

In digital signal processing and related fields, the input signal is typically sampled to produce a discrete-time sequence, which is the sisendsignaalist. Its characteristics include sampling rate, resolution, and dynamic range. Important considerations include adherence to the sampling theorem, handling of aliasing, and control of noise and distortion that affect the recorded data.

Applications of the sisendsignaalist include system identification, controller design, filter implementation, and performance testing. By analyzing how a system responds to the input signal, engineers can create or validate mathematical models, tune control strategies, and verify simulations.

Data representation and preprocessing are common steps with the sisendsignaalist. It can be stored as a time-domain vector of samples or transformed into the frequency domain for spectral analysis. Preprocessing steps such as detrending, filtering, or normalization are often applied before deeper analysis.
