In recent years, digital RF receiver technology has made
significant progress, mainly due to the availability of
high-speed ADCs. The direct conversion, IF sampling
and software defined radio architectures are becoming
common practice in the modern RF receiver design.
Due to ongoing advances in chip manufacturing and
ADC design technologies, many of the Digital Signal
Processing (DSP) functions, which used to be in separate
devices or done by software, are now included in
the ADC itself.
