DELTA SIGMA MODULATION , Drawback of Conventional Delta Modulation , use of Integrator
Digital electronicsadminDrawback of Conventional Delta Modulation , use of Integrator :- DELTA-SIGMA MODULATION (U.P. Tech. Sera. Exam, 2004-05) (10 Marks) 4.29.1 Drawback of Conventional Delta Modulation The quantizer input in the conventional delta modulator can be considered as an approximation to the derivative of the input message signal. Hence, the noise results in an accumulated error in the demodulated signal. This is the drawback of the conventional delta modulator. This drawback can be overcome by using the delta sigma modulator. In the delta sigma modulator, the input sign is […]
