Traditionally in a receiver (as shown in Figure 2.1), upon mixing the input signal from RF to IF, subsequent demodulation can be performed in a couple of ways, depending on the kind of modulation used. In the case of DECT, since the input signal is phase modulated (GMSK for DE4CT), MSK demodulation for the digital encoded phase information should be ...

As we have seen in Chapter 1, the registration of pulses corresponding to selected events is performed in digital devices. Therefore it is necessary to digitize the analog information carried by the pulse, i.e. to decide whether or not and where a given pulse should be registered.

Time-interleaved analog-to-digital converters
2009This thesis describes the feasibility of an analog-to-digital converter (ADC) with a sample-rate of 1-2 GS/s, a resolution of 8-10 bits, and a state-of-the-art power efficiency of less than 1 pJ/conversion step. The time-interleaved architecture exploits parallelism to increase the sample-rate while maintaining good power efficiency, and therefore it ...

Optical neural-net analog-to-digital converter
Optics Letters, 1989A parallel analog-to-digital converter with neuronlike elements is designed and optically implemented. Its operation principle is the simultaneous estimation of bit values for a given analog input. Architecture of the proposed analog-to-digital converter is simpler than that of an earlier one designed by the energy-minimization technique, and its ...

Analog-to-digital converters (ADCs) are critical to instrumentation and data acquisition systems, providing the interface and transformation of analog information to a digital format for computation and storage. Multi-channel ADCs are used in space avionic systems to capture information simultaneously from multiple sensor interfaces and process it ...

Oversampled Analog-to-Digital Converters
1993Oversampled Analog-to-Digital conversion has been demonstrated to be an effective technique for high resolution analog-to-digital (A/D) conversion that is tolerant of process imperfections. The design of analog modulators for oversampled analog-to-digital converters can be divided into two main categories, the multistage or cascaded modulator (MASH ...

An Analog-to-Digital Converter
Transactions of the I.R.E. Professional Group on Electronic Computers, 1953A shaft position to binary number converter suitable for use as an input device for a digital computer is described. The basic component of the converter is a binary mechanical revolution counter having an output in the form of voltages or pulses on parallel lines representing, in the binary number system, the quantity stored in the counter ...
