A computer implemented method converts a data set of a first type to a data set type of a second type. The method includes casting up a first data set of a first type to a prescribed data set type that is large enough to encompass a data set of a second type. The method then includes casting down the casted up first data set from the prescribed data set type to the second data set of the second data set type.

An arrangement for a time interleaved analog-to-digital converter that converts an signal to a digital signal and has a converter array with a plurality of analog-to-digital converters arranged in a fixed sequence in parallel with one another and can be operated with staggered timing with respect to one another is disclosed. The arrangement has a connection network which, for the purposes of actuation with staggered timing, generates in each case one control signal for an individual analog-to-di...

Illustrative binary networks for analog/digital converters are described. For instance, an analog/digital converter may operate in accordance with a principle of successive approximation, and may include a plurality of N+1 circuit nodes each representing one of N binary weights and M.gtoreq.1 redundant binary weights, wherein each binary weight corresponds to a different position of a redundant binary code formed as part of the approximation. Illustrative methods of operation of the binary netwo...

A method is described for adjusting soft values in a code block prior to decoding. A count of saturated soft values in a code block is determined and one or more of the soft values in the code block are adjusted based on the count of saturated soft values. The count may be determined by incrementing the count for each positive saturated soft value and decrementing the count of each negative saturated soft value. The soft values may be adjusted by adding an offset computed based on the count to t...

In general, this disclosure is directed to techniques for memory efficient and low complexity adaptive variable length coding (VLC) of data for a variety of applications, such as coding of digital video, image, audio, or speech data. In some aspects, the techniques may exploit properties of particular sets of codewords to support very compact data structures. In other aspects, the techniques may support low-complexity, adaptive encoding and decoding of binary sequences produced by memoryless sou...

Integrators are electronic components used to condition received analog signals, for example prior to Analog to Digital Conversion. Wide dynamic range, high gain and fine resolution are required of integrators and Analog to Digital Converters in order to limit the effects of noise, including quantization noise. Conventional integrators preceding Analog to Digital Converters are not capable of effectively meeting these requirements. A novel phase domain integrator that can meet effectively these ...

An integration type A/D converter in which a dynamic range is enlarged while keeping a simple circuit configuration is provided. Offset potential of an integrator is to be variable. Specifically, offset potential in proportion to input potential is supplied to the integrator. Since an operation point of the integrator is changed in accordance with the input potential, a dynamic range can be enlarged. Further, reference potential input to the integrator in discharging is to be variable. Specifica...
