摘要： In an analog-digital converter, a sine signal angle-modulated with noise or pseudonoise is used as a dither signal. The dither signal is superposed on an analog useful signal that is to be digitized. This signal is then digitized. The dither signal is then filtered out to produce the digitized useful signal.

摘要： A method for synchronizing to a CDMA-signal that contains a pilot sequence, overlaid with data sequences, comprises the following process steps: correlating the total signal consisting of the transmitted pilot sequence and transmitted data sequences with a reference pilot sequence; subtracting the correlation result time-delayed by one or more symbol durations of the pilot sequence from the current correlation result in order to suppress the pilot sequence and subsequent incoherent averaging, and determining the minimum.

摘要： To reduce linearity error influences in a HF circuit, particularly in an A/D converter, an input signal of the circuit is multiplied by a first auxiliary signal, and an output signal of the circuit is multiplied by a second auxiliary signal, the first and second auxiliary signals being selected such that a harmonic spectrum of the circuit is broadened.
