means is different from that of either couplet; as,
3:6::8:16, 3 bearing the same proportion to 6 as 8 does to
16. But 3 is not to 6 as 6 to 8. It is thus opposed to
continued or continual proportion; as, 3:6::12:24.

as number, and is opposed to continued quantity, as
duration, or extension.

(foldoc) | discrete
A description of a quantity whose value is one
of a fixed set of values, as opposed to a continuous - a
value capable of infinitessimal variation. For example,
integers are discrete values whereas real numbers are
continuous; digital sound has discrete amplitude leves
whereas analog sound is continuous.

discrete cosine transform
(foldoc) | discrete cosine transform
(DCT) A technique for expressing a waveform as a
weighted sum of cosines.
The DCT is central to many kinds of signal processing,
especially video compression.
Given data A(i), where i is an integer in the range 0 to N-1,
the forward DCT (which would be used e.g. by an encoder) is:
B(k) = sum A(i) cos((pi k/N) (2 i + 1)/2)
i=0 to N-1
B(k) is defined for all values of the frequency-space variable
k, but we only care about integer k in the range 0 to N-1.
The inverse DCT (which would be used e.g. by a decoder) is:
AA(i)= sum B(k) (2-delta(k-0)) cos((pi k/N)(2 i + 1)/2)
k=0 to N-1
where delta(k) is the Kronecker delta.
The main difference between this and a {discrete Fourier
transform} (DFT) is that the DFT traditionally assumes that
the data A(i) is periodically continued with a period of N,
whereas the DCT assumes that the data is continued with its
mirror image, then periodically continued with a period of 2N.
Mathematically, this transform pair is exact, i.e. AA(i) ==
A(i), resulting in lossless coding; only when some of the
coefficients are approximated does compression occur.
There exist fast DCT algorithms in analogy to the {Fast
Fourier Transform}.

discrete fourier transform
(foldoc) | discrete Fourier transform
DFT
(DFT) A Fourier transform, specialized to the
case where the abscissas are integers.
The DFT is central to many kinds of signal processing,
including the analysis and compression of video and sound
information.
A common implementation of the DFT is the {Fast Fourier
Transform} (FFT).
See also discrete cosine transform.

EDSAC
(EDSAC, often "Electronic Delay Storage
Automatic Computer") Based upon the EDVAC (Electronic
Discrete Variable Automatic Computer) designed in 1945, the
EDSAC was completed in 1949 at the University of Cambridge
Mathematical Laboratory in England. The EDSAC performed its
first calculation on 1949-05-06. EDSAC was considered to be
the first computer to store programs. It ceased to exist in
about 1951.
