Abstract
A remote terminal includes a receiver stage for receiving a transmitted signal and for delivering an analog signal. The remote terminal further includes an analog/digital converter for converting the analog signal to a digital signal, and a processing stage for processing the digital signal. The analog/digital converter is a delta-sigma converter having adjustable parameters, and the processing stage includes a tuning circuit for adjusting these parameters on the fly as a function of the transmission standard, of the actual rate of transmission of the useful data, and of the actual conditions of reception.
