This paper is mainly tutorial in nature and discusses architectures for oversampling converters with a particular emphasis on those which are well suited for high frequency input signal bandwidths. The first part of the paper looks at various architectures for discrete-time modulators and looks at their performance when attempting high speed operation. The second part of this paper presents som...

near Canterbury, Mr. Buchanan, who lost both parents when he was only seven years old, was educated at Christ's Hospital, where he became a Grecian, as members of the top form are called. Few schools have been more identified with men of letters, and it was therefore fitting that Mr. Buchanan should, after matriculation, have won a scholarship at London University for Classics and English Liter...

A number of recent visual-word recognition and reading experiments have concluded that the upper part of words is more important for lexical access than is the lower part, which conforms with Huey's (1908) observation. Here, we examined whether this phenomenon may simply be due to the fact that words in Indo-European languages tend to have a higher number of confusable letters in the lower than...

Since a genome is a discrete sequence, the elements of which belong to a set of four letters, the question as to whether or not there is an error-correcting code underlying DNA sequences is unavoidable. The most common approach to answering this question is to propose a methodology to verify the existence of such a code. However, none of the methodologies proposed so far, although quite clever,...

ing away from the conflation process itself, the argument structure of sneeze of (1a) is as follows:

A generalized word in two letters A and B is an expression of the form W = Aα1Bβ1Aα2Bβ2 · · ·AαNBβN in which the exponents are nonzero real numbers. When independent positive definite matrices are substituted for A and B, it is of interest whether W necessarily has positive eigenvalues. This is known to be the case when N = 1 and has been studied in case all exponents are positive by two of the...

In an earlier study (Cartwright and Tucker, 1967) we explored the possibility of reducing the number of calls on an interview inquiry by writing to people beforehand asking when they were most likely to be in. That experiment was unsuccessful: more people replied saying that they did not want to be interviewed than wrote telling us suitable times to call, and the final response rate in the expe...
