Mathematical basics of bandlimited sampling and aliasing
Jan 1, 2005
By Vladimir Vitchev Modern applications often require that we sample analog signals, convert them
to digital form, perform operations on them, and reconstruct them as analog
signals. The important question is how to sample and reconstruct an analog
signal while preserving the full information of the original....

SDR platform enables reconfigurable direction finding system
Jan 1, 2005
By Jyothsna Rajan A software-defined radio (SDR) transceiver platform is used to implement a
reconfigurable direction finding (DF) system. This article will describe the
intended data flow and data rate requirements of a typical DF system, map the
DF software components to the SDR platform, and demonstrate the availability
of resources for more complex implementations....
