Complex embedded systems often have multiple signals that need to be monitored in the time and frequency domains. Although the baseband digital, RF, and analog signals are interdependent, their ...

Analytical and experimental background for the fundamental understanding of time and frequency domain signals, required for digital signal processing, vibration, and acoustic signal analysis.

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 ...

In many applications, resampling an already digitized signal is mandatory for an efficient system design. In wireless communications, sample rate conversion is typically utilized for upconversion and ...

A basic Fourier transform identity coupled with an iterative convergence algorithm provides a powerful method to align band-limited signals. Recently, I wrote automated test software for a ...

When analyzing data, one can use a variety of transformations on the data to massage it into a form that works better to tease out the information one is interested in. One such example is the ...

Metasurfaces are artificial array structures consisting of subwavelength unit cells arranged on a specific two-dimensional surface. Dynamic, reconfigurable metasurfaces are an excellent way to ...
