Oscilloscopes are time-domain instruments, but because they digitize waveforms, oscilloscopes can process time-domain signals into the frequency domain. The FFT (Fast Fourier Transform), spectrum ...

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 ...

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 ...

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 ...

The basic concepts underpinning time-domain reflectometry. Difference between frequency- and time-domain analysis. Some applications of TDR measurements. Time-domain reflectometry (TDR) is a technique ...
