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 ...

The Fourier transform takes a signal/function from the time domain into the frequency domain. It indicates what frequencies are present in a time domain waveform. Consider a sine wave with a ...

A brief introduction to quadrature signals Let's now focus on describing a quadrature signal, having a real and an imaginary part, that is a function time. To do so we must remember that, as the great ...

Frequency domain analysis PSD, power per unit frequency, is the most common frequency domain tool for noise analysis. Figure 6 shows an example. The upper trace is the time view of the bandlimited ...

“Time-domain reflectometry” sure sounds like something that needs racks of expensive equipment to accomplish. In reality, TDR is just measuring the time between injecting a pulse into a cable ...
