Method of Definition of the Basic Parameters of the Sampled and Reconstructed Signals

The paper is dealing with the basics of the sampling and reconstruction theory and practice and especially with the evaluation of the sampled and directly reconstructed signal. The approach is based on the principles of the geometry because the simplest electrical test signals could be considered as existing into single plane coordinate system with two perpendicular axs X and Y or axes Time and Amplitude . The method is making possible the evaluation of the differences called “errors” between the corresponding parameters of the original analog test signal and its approximation with rectangular and trapezoidal like staircase function. Examples with sinusoidal signals based on the model “take and memorize until next sample” are given.
