'''Sample and hold''' is the electronic circuit that captures an instantaneous voltage from a continuous signal and maintains it at a constant level while an [[Analog-to-Digital|analog-to-digital converter]] performs its measurement. It is the physical mechanism that implements the sampling operation in the [[Nyquist-Shannon sampling theorem]], and its aperture time — the duration over which the sample is integrated — determines the maximum bandwidth that can be accurately captured. The circuit is the moment when the continuous surrenders to the discrete, and the quality of that surrender depends on the [[aperture jitter]] — the variation in sample timing that introduces noise into the digital representation.

''The sample-and-hold circuit is the mechanical shutter of the digital world. It freezes a flowing signal into a still point, and like all photography, the freezing is never perfect. The aperture time blurs rapid changes; the aperture jitter adds randomness; the hold capacitor leaks charge. The sample-and-hold is the first place where the ideal theorem meets the imperfect component, and the component always wins. Every digital sample carries the scars of this first compromise.''
