2. Oscilloscope types - Wikipedia

   en.wikipedia.org/wiki/Oscilloscope_types

   Digital technology allows the information to be displayed with brightness, clarity, and stability. There are, however, limitations as with the performance of any oscilloscope. The highest frequency at which the oscilloscope can operate is determined by the analog bandwidth of the front-end components of the instrument and the sampling rate.

3. Tektronix analog oscilloscopes - Wikipedia

   en.wikipedia.org/wiki/Tektronix_Analog_Oscilloscopes

   The S-1 sampling head ($1,160 in 1983) had a 1 GHz bandwidth; the S-4 sampling head ($2,665) had a 25 ps risetime 12.4 GHz bandwidth traveling-wave sampler. The 7S11 would work in combination with the 7T11 ($4,460 in 1983) or 7T11A sampling sweep units as a time base.

4. Oscilloscope - Wikipedia

   en.wikipedia.org/wiki/Oscilloscope

   A standard DSO is limited to capturing signals with a bandwidth of less than half the sampling rate of the ADC (called the Nyquist limit). There is a variation of the DSO called the digital sampling oscilloscope which can exceed this limit for certain types of signal, such as high-speed communications signals, where the waveform consists of ...

5. Sampling (signal processing) - Wikipedia

   en.wikipedia.org/wiki/Sampling_(signal_processing)

   When analog video is converted to digital video, a different sampling process occurs, this time at the pixel frequency, corresponding to a spatial sampling rate along scan lines. A common pixel sampling rate is: 13.5 MHz – CCIR 601, D1 video; Spatial sampling in the other direction is determined by the spacing of scan lines in the raster. The ...

6. Nyquist rate - Wikipedia

   en.wikipedia.org/wiki/Nyquist_rate

   Fig 1: Typical example of Nyquist frequency and rate. They are rarely equal, because that would require over-sampling by a factor of 2 (i.e. 4 times the bandwidth). In signal processing, the Nyquist rate, named after Harry Nyquist, is a value equal to twice the highest frequency of a given function or signal

7. Nyquist–Shannon sampling theorem - Wikipedia

   en.wikipedia.org/wiki/Nyquist–Shannon_sampling...

   The Nyquist–Shannon sampling theorem is an essential principle for digital signal processing linking the frequency range of a signal and the sample rate required to avoid a type of distortion called aliasing. The theorem states that the sample rate must be at least twice the bandwidth of the signal to avoid aliasing.

8. Downsampling (signal processing) - Wikipedia

   en.wikipedia.org/wiki/Downsampling_(signal...

   Both downsampling and decimation can be synonymous with compression, or they can describe an entire process of bandwidth reduction and sample-rate reduction. [ 1 ] [ 2 ] When the process is performed on a sequence of samples of a signal or a continuous function, it produces an approximation of the sequence that would have been obtained by ...

9. Sample-rate conversion - Wikipedia

   en.wikipedia.org/wiki/Sample-rate_conversion

   Sample-rate conversion, sampling-frequency conversion or resampling is the process of changing the sampling rate or sampling frequency of a discrete signal to obtain a new discrete representation of the underlying continuous signal. [1]
