With the advent of higher broadband speeds in the fixed line and wireless systems, the need for higher performing data converters has become apparent. In this article, we discuss the different standards that are pushing this trend and how single tone testing, in some cases, does not accurately determine the performance in communication systems. This is particularly true in systems that employ multi-tone signaling or OFDM (orthogonal frequency division multiplexing), in which the available bandwidth is split into a large number of sub-channels, which then allows data to be transmitted over many sub-carriers thereby enabling higher data rates.
