A/D and D/A Conversion,analog to digital and digital to analog


Data Converter impacts the factor for the performance of the overall radio design
Requirements: very high sampling rates, high number of effective quantization bits, an operating bandwidth of several Ghz, a large spurious-free dynamic range, a reasonable price
DAC and ADC converters
Sampling and Quantization
Nyquist Zones
Aliasing
Bandpass filtering – uses image to translate bandpass signals to baseband
Errors occurs in Quantization

Abstract:

Digital audio broadcasting, DAB, is the most fundamental advancement in radio technology since that introduction of FM stereo radio. It gives listeners interference - free reception of CD quality sound, easy to use radios, and the potential for wider listening choice through many additional stations and services.

DAB is a reliable multi service digital broadcasting system for reception by mobile, portable and fixed receivers with a simple, non-directional antenna. It can be operated at any frequency from 30 MHz ....etc

Digital-to-Analog Analog-to-Digital
Data Handling Systems
Both data about the physical world and control signals sent to interact with the physical world are typically analog or continuously varying quantities.
In order to use the power of digital electronics, one must convert from analog to digital form on the experimental measurement end and convert from digital to analog form on the control or output end of a laboratory system.
Digital-to-Analog Conversion
When data is in binary form, the 0's and 1's may be of s ....etc
