Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

This chapter covers the following subjects: Wireless Local-Area Networks: A brief history of wireless networking and some of the basic concepts. How Bandwidth Is Achieved from RF Signals: The ...
