Figure 1: Windowing a waveform that's not periodic within the acquisition window reduces spectral leakage The second artifact in FF...

Figure 1: The first precondition of using the Fourier transform is a repetitive signal Our last post discussed how time-domain signals ...

Figure 1: A fundamental underlying assumption of a discrete Fourier transform is a repetitive waveform Fundamentally, oscilloscopes a...

Figure 1: A coaxial cable presents high impedance at low frequencies but acts as a transmission line at higher frequencies In our recen...

Figure 1: Shown is a comparison of inherent oscilloscope noise and noise at the shorted tip of a 10x passive probe Now that we have a b...

Figure 1: With unequal impedances at either end of the coax, are cable reflections a concern in 10x passive probes? We've been disc...

Figure 1: Shown are FFT plots of a 10-MHz, fast-edge square wave reaching the oscilloscope via direct coax connection (orange-yellow plo...
