A Boucherot cell (or Zobel network) is an electronic filter, used in audio amplifiers to damp high-frequency oscillations that might occur in the absence of loads at high frequencies. Named after Paul Boucherot a Boucherot cell typically consists of a resistor and capacitor in series, usually placed across a load for stability.
Snubbers allow for free thermal movement of a component during regular conditions, but restrain the component in irregular conditions. [6] A hydraulic snubber allows for pipe deflection under normal operating conditions. When subjected to an impulse load, the snubber becomes activated and acts as a restraint in order to restrict pipe movement. [7]
The usual method used for suppressing EMI is by connecting a snubber network, a resistor in series with a capacitor, across a pair of contacts. While this may offer modest EMI reduction at very low currents, snubbers do not work at currents over 2 A with electromechanical contacts. [13] [14]
As an arctic blast hits the Northeastern U.S. this weekend, a clipper system moving across the Great Lakes and into the Northeast early next week is bringing a chance of snow -- and rain -- for ...
She overcame that anxiety and set out to make history. Among her accomplishments managing the U.S. government's largest agency was a significant step for Indigenous communities.
For the first seven weeks of the MLB offseason, the first-base market was frozen. Despite a wealth of intriguing candidates to change threads in both free agency and on the trade block, there was ...
Christmas seals are adhesive labels that are similar in appearance to postage stamps that are sold then affixed to mail during the Christmas season to raise funds and awareness for charitable programs. Christmas seals have become particularly associated with lung diseases such as tuberculosis, and with child welfare in general. They were first ...
The Stochastic Neural Analog Reinforcement Calculator (SNARC) is a neural-net machine designed by Marvin Lee Minsky. [ 1 ] [ 2 ] Prompted by a letter from Minsky, George Armitage Miller gathered the funding (a few thousand dollars) for the project from the Office of Naval Research in the summer of 1951 with the work to be carried out by Minsky ...
