Both the digital to analog and the analog to digital are ofsignificance in some applications of digital signal processing. Butin most of the cases the conversion of digital signal to analog isalways more effective than converting analog signal to digitalbecause digital signal to analog conversion is less expensive,flexible and more reliable than analog to digital conversion. Noisecan be easily detected in Digital Communication as compared toAnalog Communication. Hence it is much preferred.
