Model Transmisi Digital Optik Isyarat Analog Dengan Modulasi Delta

Abstract

This paper describes about making digital signal transmission model using delta modulation. Model that build consist of transmiter and reciver side. Main part of this model is integrator which changing series digital pulse into staircase signal with fixed step for every high and low pulse. Experiment result show that the model able to do modulation and demodulation process well and could show the slope overload condition. Integration step used is 0,4 volt with frequency sampling at 125 KH
