In the regenerative circuit discussed here, the active device also functions as a detector; this circuit is also known as a regenerative detector. [16] A regeneration control is usually provided for adjusting the amount of feedback (the loop gain). It is desirable for the circuit design to provide regeneration control that can gradually ...
Sample times. Sample and hold. A sample-and-hold integrated circuit (Tesla MAC198) 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 ...
The idea of positive feedback was already current in the 1920s with the introduction of the regenerative circuit. [11] Friis & Jensen (1924) described regeneration in a set of electronic amplifiers as a case where the "feed-back" action is positive in contrast to negative feed-back action, which they mention only in passing. [12]
sample and hold A circuit that takes a sample of a changing analog value and holds onto it until the value can be processed by some other stage. sampling The process of taking a continually varying signal and turning it into a stream of numbers taken at regular intervals. sampling frequency The rate at which an analog value is sampled. satellite
The IRS said it's sending out checks worth up to $1,400 to 1 million people. Here's what to know about the "special payments."
While many health-food buzzwords get thrown around a lot on social media and people usually know they mean something good or bad, they can't often say why.Organic
A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
An Indiana death row inmate convicted of murdering his brother, his sister's fiancé and their two friends because he thought they were talking about him behind his back is a day away from execution.
