Utility frequency. The utility frequency, (power) line frequency ( American English) or mains frequency ( British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user. In large parts of the world this is 50 Hz, although in the Americas ...
American Automobile Association ( AAA – commonly pronounced as " Triple A " but also pronounced as individual letters) is a federation of motor clubs throughout North America. AAA is a privately held not-for-profit national member association and service organization with over 60 million members [ 1] in the United States and Canada. [ 2]
Hertz Global Holdings, Inc. (formerly The Hertz Corporation ), known as Hertz, is an American car rental company based in Estero, Florida. The company operates its namesake Hertz brand, along with the brands Dollar Rent A Car, Firefly Car Rental and Thrifty Car Rental . It is one of the three big rental car holding companies in the United ...
Sample-rate conversion, sampling-frequency conversion or resampling is the process of changing the sampling rate or sampling frequency of a discrete signal to obtain a new discrete representation of the underlying continuous signal. [ 1] Application areas include image scaling [ 2] and audio/visual systems, where different sampling rates may be ...
The refresh rate, also known as vertical refresh rate or vertical scan rate in reference to terminology originating with the cathode-ray tubes (CRTs), is the number of times per second that a raster-based display device displays a new image. This is independent from frame rate, which describes how many images are stored or generated every ...
The hertz is defined as one per second for periodic events. The International Committee for Weights and Measures defined the second as "the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom" [3] [4] and then adds: "It follows that the hyperfine splitting in the ground state of the ...
In a bizarre series of events early Monday morning, a hotel desk clerk in La Jolla, California, stabbed a guest before fleeing and driving his car off a pier, according to San Diego police.
Nyquist–Shannon sampling theorem. The Nyquist–Shannon sampling theorem is an essential principle for digital signal processing linking the frequency range of a signal and the sample rate required to avoid a type of distortion called aliasing. The theorem states that the sample rate must be at least twice the bandwidth of the signal to avoid ...
