Work in Progress: Studying the analog to digital signal conversion process through examples using GNU Radio

This paper describes the advances in developing a hands-on laboratory experience on analog to digital signal conversion process using GNU Radio. This conversion process is fundamental to the communication systems since it simplifies the networks. It is not necessary to have one network for analog services and another for digital ones. The analog signals must have bandwidth and amplitude limited before being converted. Then, the sample rate, the number of bits and the quantification strategy are important to determine the approximation error between the quantified signal and the analog (original) one, known as quantification noise. These concepts are key at any introductory communication system courses. The challenge is to provide an experimental environment by a deliverable software tool, where students could experiment the effect of varying certain parameters such as signal bandwidth, sample rate, the number of bits or the quantification strategy through self practice, in an amusing manner.
