We take this frequency domain spectrum and turn it back into a time domain signal. We measure the 10-90 rise time of the resulting signal. Figure 2 shows the recreated time domain waveforms from these ...

Anytime the frequency spectrum of a signal is altered, its time domain performance will be altered too. Consider the spectrum of the 1-GHz square wave of Figure 1d.

Advances in processing and bandwidth for signal analyzers and oscilloscopes, respectively, make them seem interchangeable for frequency-domain analysis, but that’s not necessarily ...
