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 ...
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 ...
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 ...
With a good DSA, analyzing the sound of one hand clapping is not a problem. A dynamic signal analyzer (DSA) is used to investigate signals representing forces and motions. In this context, the word ...
