Learning module of non-periodic signal digitization using ATMega328 microcontroller

Goal of the paper is to describe basic steps of continuous signal digitization. The article deals mainly with the process of sampling and linear scalar quantization. The issues of source code operation are described in brief. Measurement of sampling frequency that influences on input signal reconstruction is designed on the basis of digitization analysis. Sampling and quantization is accomplished using ATMega328P microprocessor. The contribution is the result of learning module designed and implementated for students at universities that focuses on processing electrical signals.
