Experimental results derived using real-time hardware together with supporting software simulations reveal that for infinite impulse response digital filters low-level chaos acts as self-dither, which both decorrelates truncation distortion and aids linearization of low-level digital-to-analog conversion nonlinearity. The process is examined for a range of filter responses, in particular those ...

A multibit analog-to-digital converter can achieve high resolution with a lower order modulator and lower oversampling ratio than a single-bit design, but it requires a multibit internal flash analog-to-digital converter rather than a simple comparator. In an implementation with a fully differential analog front end, the flash analog-to-digital converter must quantize a differential voltage rel...

The application specific paper describes a design approach for digital magnetic sensors Practical realizations are based on the Universal Frequency-to-Digital Converter (UFDC-1). By eliminating the need for ADC, the frequencyor duty-cycle-to-digital conversion schemes reduce the systems complexity. The results of such design approach are high-performance digital magnetic sensors with truly digi...

OBJECTIVES To provide the practicing surgeon with data to make an informed economic decision regarding conversion from analog to digital photography. METHODS A cost analysis of photography based on 35-mm vs digital platforms (low-, medium-, and high-cost hardware). RESULTS Break-even thresholds for the investment in a digital platform of low, medium, and high costs were 3674, 15,789, and 34...

This paper discusses the process of behavioral conversion of digital circuits used for signal processing applications into its neural network counterpart. The neural network so devised represents simulated digital circuits without any deviation in its input–output characteristics. However, the design of such networks depends entirely on different parameters and thus the design process too. It i...

The adoption of existing technologies for digital curation, most especially digital capture, is outlined in the context of personal digital archives and the Digital Manuscripts Project at the British Library. Technologies derived from computer forensics, data conversion and classic computing, and evolutionary computing are considered. The practical imperative of moving information to modern and...

A high performance digital audio amplifier system requires an asynchronous sample rate converter to synchronize the input digital data stream to the low jitter system clock used to generate the digital PWM output. By performing the sample rate conversion with highly oversampled signals the computation and memory requirements are minimized. The performance of the digital amplifier system is not ...
