Newspapers are considered to be the first draft of history, while at the same time, are part of a country’s cultural heritage. By converting newspaper archives to digital resources we achieve digital preservation in terms of preventing paper deterioration as well as providing full utilization of the archives by all interested parties. In this paper, we present a series of applications pertainin...

Problem statement: With the advent of the advanced technology and the need for more advanced equipment, the current progress and development of electronic instruments stimulate more interest and efforts for more innovative ideas and better designs. Many real world physical values, such as sounds, temperature, pressure and humidity, can be measured as analog or continuous signals. However, to pr...

The concept of time-domain reference-ladder for the implementation of fully-digital flash-ADCs is proposed in this work. The complete reference ladder is implemented using only digital circuits. Based on this concept, a flash ADC is proposed and implemented in this work using digital circuits, one comparator and a customized sample-and-ramp circuit. An unconventional time-to-digital conversion ...

A novel approach for direct analog-to-residue conversion is presented in this chap/er using the most popular sigma-della analog-to-digital converter. This converter provides high resolulion. high conversion speed and a low cost for implementation. The non-positional nature (~f RNS makes it suitable for fault-toleranl architectures. The error detection and correction properties (?f Redundant Res...

Despite the popularity of digital devices, real world signals are typically represented by analog signals. Digital control systems process real world analog signals by using an analog-to-digital converter (ADC) to convert analog signals to digital. Conversions back to analog signals are accomplished using a digital-toanalog converter (DAC). Maxim offers a complete line of precision DACs from 8 ...

Data acquisition and conversion systems interface between the real world of physical parameters, which are analog, and the artificial world of digital computation and control. With current emphasis on digital systems, the interfacing function has become an important one; digital systems are used widely because complex circuits are low cost, accurate, and relatively simple to implement. In addit...

An analog-to-digital converter for on-chip focal-plane image sensor applications. The analog-to-digital converter utilizes a single charge integrating amplifier in a charge balancing architecture to implement successive approximation analog-to-digital conversion. This design requires minimal chip area and has high speed and low power dissipation for operation in the 2-10 bit range. The inventio...

In many practical applications of digital signal processing sampling rate conversion is a problem. The process of converting a signal from a given rate to a different rate is called Sampling Rate Conversion. Sampling rate conversion process may be based on an integer or a rational factor. In this paper, the process of rational sampling rate conversion is discussed in detail. Along with this, a ...
