Introduction. A digital signal is superior to an analog signal because it is more robust to noise and can easily be recovered, corrected and amplified. For this reason, the tendency today is to change an analog signal to digital data. In this section we describe two techniques, . . Juri . Minxha. Medical Image Analysis. Professor Benjamin Kimia.
