Data acquisition can be divided into the steps shown in Figure 43.


Figure 43: Data Acquisition

The following section will describe each step of the data acquisition process, especially as they are relevant to the HCI designer. Two good references for this subject are Digital Signal Processing: A Practical Approach, 1993 by Ifeachor and Jervis and A Digital Signal Processing Primer with Applications to Digital Audio and Computer Music, 1996 by Steiglitz.
