Minimum frequency-shift keying or minimum-shift keying (MSK) is a particular spectrally efficient form of coherent FSK. In MSK, the difference between the higher and lower frequency is identical to half the bit rate. Consequently, the waveforms that represent a 0 and a 1 bit differ by exactly half a carrier period.
Pixel shift. This very fine level of resolution was derived by merging four precursor images taken at sensor positions just one pixel apart. Comparison of simple image (left) and image generated with pixel shift (right) (Click to enlarge) Pixel shift is a method in digital cameras for producing a super resolution image.
The Alt key Alt (pronounced / ɔːlt / AWLT or / ʌlt / ULT) on a computer keyboard is used to change (alternate) the function of other pressed keys. Thus, the Alt key is a modifier key, used in a similar fashion to the Shift key. For example, simply pressing A will type the letter 'a', but holding down the Alt key while pressing A will cause ...
the free encyclopedia that anyone can edit. "Cross Road Blues" is a song written by the American blues artist Robert Johnson. He sang it as a solo piece with acoustic slide guitar in the Delta blues style. The lyrics describe Johnson's grief at being unable to catch a ride at an intersection before the sun sets.
In digital modulation, minimum-shift keying ( MSK) is a type of continuous-phase frequency-shift keying that was developed in the late 1950s by Collins Radio employees Melvin L. Doelz and Earl T. Heald. [1] Similar to OQPSK, MSK is encoded with bits alternating between quadrature components, with the Q component delayed by half the symbol period.
AltGr key. The AltGr key is the first key to the right of the space bar. AltGr (also Alt Graph) is a modifier key found on many computer keyboards (rather than a second Alt key found on US keyboards). It is primarily used to type special characters and symbols that are not widely used in the territory where sold, such as foreign currency ...
RSA ( Rivest–Shamir–Adleman) is a public-key cryptosystem, one of the oldest widely used for secure data transmission. The initialism "RSA" comes from the surnames of Ron Rivest, Adi Shamir and Leonard Adleman, who publicly described the algorithm in 1977. An equivalent system was developed secretly in 1973 at Government Communications ...
978-0-385-12991-6. Followed by. Different Seasons. Night Shift is Stephen King 's first collection of short stories, [1] first published in 1978. In 1980, Night Shift won the Balrog Award for Best Collection, and in 1979 it was nominated as best collection for the Locus Award and the World Fantasy Award. [2]
