THD+N Versus Frequency Characteristics and Spectra of the PCM1717/18/19/20/23/27
PDF, 107 Kb, Archivo publicado: sept 27, 2000
The following application bulletin describes the theory and actual performance of THD+N versus frequency characteristics for the PCM1717 series which include on-chip digital filters. The contents of this article apply to the PCM1717 and other devices which use the same digital filter architecture and delta-sigma DAC, such as PCM1718, PCM1719, PCM1720, PCM1723, and PCM1727.

A Low Noise, Low Distortion Design for Antialiasing and Anti-Imaging Filters
PDF, 62 Kb, Archivo publicado: sept 27, 2000
In any digitizing system, antialiasing and anti-imaging filters are used to prevent the signal frequencies from folding back around the sample frequency and causing false (or alias) signals from appearing in the signal we are attempting to digitize. Very often, these filters must be very complex, high order analog filters in order to do their job effectively.
