(...continued)   In summary, the useful throughput of a digital system is a function of many parameters. While it is clear that the throughput rate can be no greater than the sum of the analog-to-digital conversions taking place, it is sometimes less obvious that other processes (digital filtering; transfer of the data to the computer; data storage, reduction and display) are often the limiting factor. Indeed, the real question of throughput is not always how much analog data can be digitized, but rather how much of the digitized data can actually be utilized.   Page 14 of 24
