Sigma-delta modulator and method for digitizing a signal

摘要

A sigma-delta modulator (10) and a method for digitizing an analog signal. The sigma-delta modulator includes at least one switch (16) for altering the order of the sigma-delta modulator (10). The order of the sigma-delta modulator (10) is changed based on the communication protocol of the received analog signal. More particularly, the order of the sigma-delta modulator (10) is increased for communication protocols having wide information-bandwidths. Alternatively, the order of the sigma-delta modulator (10) is decreased for communication protocols having narrow information-bandwidths.
