INTRODUCTION TO DIGITAL SIGNAL PROCESSING
classes.engineering.wustl.eduTo carry out any digital signal processing, most real-world signals, which are predominately analog, must be converted to digital form. Although the process is conceptually straightforward – just feed the analog signal to an analog-to-digital converter – there are a number of issues connected with that process that must be considered.
