First, let's go over the basics of signal sampling. Sampling is fundamental to digital signals The Nyquist Theorem states that information signals must be sampled at a rate at least twice as high as ...

Sampling is the digital equivalent of amplitude modulation. The digital carrier (repetitive sampling pulses) is amplitude modulated by the video signal, resulting in a wide modulation spectrum with ...

The oscilloscope's sampling rate sets its timing resolution. For example for a 100 MHz signal, each degree in phase translates into 27 ps. Clearly, for a one-degree phase measurement accuracy, the ...

the original analog signal can be perfectly recovered from the discrete values produced by sampling.” If you want to know more, you can go and read about it here. The easiest way to remember it ...

The signal modulation and bandwidth are retained, but the sampling-rate requirements are much lower. The superhet has some downsides, though. First, it requires many circuits and filters ...
