A software-defined radio (SDR) terminal promotes programmable realizations of the physical layer functionalities. A lot of research work has been done in applying DSPs and FPGAs to implement the ...

CML Microcircuits unveiled a new I/Q modulator in its family of RF integrated circuits. The CMX993 is a highly integrated, general-purpose RF quadrature modulator that operates between 100 MHz to 1 ...

Despite the need for an IC, this ubiquitous interface between the modulator and audio-video signals has not been reduced to an integrated circuit. The major reasons for that deficiency are the ...

In high-speed wireless communications systems, signals must be translated in frequency by up-conversion or down-conversion for signal propagation and processing. Traditionally known as mixing, this ...

With numerous step-by-step tutorials and practical design examples, this book gradually develops the reader s in-depth understanding of essential concepts in high-performance switched-capacitor ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

In the last years, a major transition from analog to digital modulation techniques has occurred and it can be seen in all areas of wireless communication, satellite and cellular systems. This paper ...
