Frequency domain tutorial, part 2: complex signals and spectral diagrams

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 ...

Creating a Frequency Plan for a System using a PLL

How do you ensure that every part of a system receives the clock it needs—without wasting power or sacrificing performance? The answer lies in creating a well-structured frequency plan built around a ...

Analog Devices Design Tools: Frequency Folding Tool, A ‘Complex’ Example

I’ve now discussed the basics of the frequency folding tool from Analog Devices in two previous blog posts this year, Analog Devices Design Tools: ADISimADC Frequency Folding Tool and Analog Devices ...
