Initially, Bazaarvoice focused on software that lets businesses add product reviews to their websites. [5] [6] Bazaarvoice later expanded to include software that allows businesses to analyze reviews, ratings, videos, social media, and other user-generated content posted by customers, [7] which is used by companies including Wal-Mart, AT&T and ...
The company evolved the system continuously through the early 1980s to integrate the first 16-bit digital sampling system to magnetic disk, and eventually a 16-bit polyphonic sampling system to memory, as well. The company's product was the only digital sampling system that allowed sample rates to go as high as 100 kHz.
The term Nyquist Sampling Theorem (capitalized thus) appeared as early as 1959 in a book from his former employer, Bell Labs, [22] and appeared again in 1963, [23] and not capitalized in 1965. [24] It had been called the Shannon Sampling Theorem as early as 1954, [25] but also just the sampling theorem by several other books in the early 1950s.
Influenster has a platform consisting of over 11 million reviews, with 880,000 new reviews generated each month. [5] These products represent over 100K consumer brands with over 1.7 million product pages for users to review, ask/answer questions, and upload photos/videos of.
This digital data stream can therefore be converted to analog by passing it through an analog low-pass filter. The DVD-Audio format uses standard, linear PCM at variable sampling rates and bit depths, which at the very least match and usually greatly surpass those of standard CD audio (16 bits, 44.1 kHz).
Audio on Compact Disc has a sampling rate of 44.1 kHz; to transfer it to a digital medium that uses 48 kHz, method 1 above can be used with L = 160, M = 147 (since 48000/44100 = 160/147). [5] For the reverse conversion, the values of L and M are swapped. Per above, in both cases, the low-pass filter should be set to 22.05 kHz.
In digital signal processing, multidimensional sampling is the process of converting a function of a multidimensional variable into a discrete collection of values ...
Data acquisition is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acronyms DAS, DAQ, or DAU, typically convert analog waveforms into digital values for processing. The ...
