Platform for studying of pulse code modulation

This paper presents an integrated platform for studying the digital transmission method named pulse code modulation. The platform consists in an experimental board and a software model that allows the measurements of significant parameters of a codec based on this communication method together with the animated visualization of the circuits operation and typical waveforms. The modeling and simulations were realized in Proteus software environment. The proposed platform represents a very useful tool in didactical process of teaching pulse code modulation principles in communication laboratories.
