DNA information: from digital code to analogue structure.
The digital linear coding carried by the base pairs in the DNA double helix is now known to have an important component that acts by altering, along its length, the natural shape and stiffness of the molecule. In this way, one region of DNA is structurally distinguished from another, constituting an additional form of encoded information manifest in three-dimensional space. These shape and stif...
متن کاملTransition from analogue-to-digital nuclear electronics for precise gamma radiation spectroscopy: advantages and limitations
In this paper, digital signal processing for precise gamma ray spectroscopy is presented. The basis of this system is a 14bit waveform digitizer which samples the output of pre-amplifier signals directly. The advantages and limitations of the digital spectrometer compared with analog spectrometer has been tested and analyzed from precise gamma ray spectroscopy point of view. The results shows t...
متن کاملFrom Analogue to Digital Speech Sounds
Sound is a medium used by humans to carry information. The existence of this kind of medium is a pre-requisite for language. It is organized into a code, called speech, which provides a repertoire of forms that is shared in each language community. This code is necessary to support the linguistic interactions that allow humans to communicate. How then may a speech code be formed prior to the ex...
متن کاملLogarithmic Analogue-to-Digital Converters
Logarithmic signal processing is a topic that exists in the communications engineer’s vocabulary for a long time. Sometimes refered as compression, it is a technique to adapt the dynamics of signals to the dynamics of the system where i t is to be processed or transmitted. Probably, the most common application of compression is the telephone system, where the voice signal is compressed to a dig...
متن کاملProportional electro-hydraulic valves: from analogue to digital control
Proportional electro-hydraulic valves are ubiquitous as flow actuators in hydraulic systems. Flow regulation is the result of the accurate positioning of a spool driven by a solenoid and a position sensor. The overall control consists of two hierarchical loops: the inner loop is the solenoid current regulator with a closed-loop bandwidth close to 1 kHz. A modelbased digital regulator of this ki...
