This document presents an overview of Joint Time-Frequency Analysis (JTFA) in terms of frequency analysis. It answers the questions of when to use JTFA and what tools are available for JTFA. One ...
Figure 4. A snapshot, in time, of two complex numbers whose exponents, and thus their phase angles, change with time. The notion of negative frequency is often troubling to engineers who've spent so ...
After an RF or microwave signal has been converted to an intermediate frequency (IF) and digitized, the type of signal processing you choose to apply determines what information is extracted from the ...
