In electronics , a sample and hold also known as sample and follow circuit is an analog device that samples captures, takes the voltage of a continuously varying analog signal and holds locks, freezes its value at a constant level for a specified minimum period of time. Sample and hold circuits and related peak detectors are the elementary analog memory devices. They are typically used in analog-to-digital converters to eliminate variations in input signal that can corrupt the conversion process. A typical sample and hold circuit stores electric charge in a capacitor and contains at least one switching device such as a FET field effect transistor switch and normally one operational amplifier. The buffer amplifier charges or discharges the capacitor so that the voltage across the capacitor is practically equal, or proportional to, input voltage. In hold mode the switch disconnects the capacitor from the buffer. The capacitor is invariably discharged by its own leakage currents and useful load currents, which makes the circuit inherently volatile , but the loss of voltage voltage drop within a specified hold time remains within an acceptable error margin for all but the most demanding applications.

It is a small board cut from a 10x16cm single-sided eurocard, and is 10cm long by just over 5cm wide. Inputs and outputs are at the bottom of the board, and the power connector is at the top. This one appears to work as described by Jeurgen Haible.

A high performance and low power dissipation operational trans-conductance amplifier OTA is realized by optimizing circuit configuration and adopting switched-capacitor dynamic bias technology.

With digital sampling comes quantization errors that create low-level noise which gets added to the reconstructed signal. The minimum analog signal amplitude that can bring about a change in the digital signal is called the Least Significant Bit LSB , while the rounding error that occurs between the analog and digital signals is referred to as quantization error. The resolution of an analog to digital converter indicating the number of discrete values it can produce over a range of analog values is typically expressed by the number of bits.

Вы думаете, он, умирая, до последний секунды переживал за несчастное АНБ. - Распадается туннельный блок! - послышался возглас одного из техников.  - Полная незащищенность наступит максимум через пятнадцать минут.

Губы Стратмора приоткрылись, произнеся последнее в его жизни слово: Сьюзан. Воздух, ворвавшийся в ТРАНСТЕКСТ, воспламенился. В ослепительной вспышке света коммандер Тревор Стратмор из человека превратился сначала в едва различимый силуэт, а затем в легенду.

Немедленно. В другой стороне комнаты зазвонил телефон. Это был Джабба. ГЛАВА 107 Сьюзан понятия не имела, сколько прошло времени.

У нее возникло ощущение, что она разговаривает с абсолютно незнакомым человеком.
