  • Author: Gary Breed
Most new wireless communica-tions, navigation and sensing technologies make extensive use of digital signal processing (DSP). Because of the cost advantages of cheap silicon DSP power over traditional RF signal processing using discrete and modular components, designers seek to minimize the RF cir-cuitry, moving the DSP closer to the antenna input. This tutorial provides a brief review of how the analog-to-digital converter (ADC) responds to signals at its input, and presents the main performance issues that are a result of that behavior.
