The widely used approach for the laboratory component of such courses involves the utilizationofMATLABtoimplementsignalsandsystemsconcepts.Thisbookpresentsanewly developedlaboratoryparadigmwhereMATLABcodesaremadetorunonsmartphones,which most students already possess. This smartphone-based approach enables an anywhere-anytime platformforstudentstoconductsignalsandsystemsexperiments.Thisbookcoversthelabora- toryexperimentsthatarenormallycoveredinsignalsandsystemscoursesanddiscusseshowto run MATLAB codes for these experiments on both Android and iOS smartphones, thus en- abling a truly mobile laboratory environment for students to learn the implementation aspects ofsignalsandsystemsconcepts.
