摘要：
A circuit configuration for a multistandard communications terminal has, for the reception of radio signals, a radio frequency component with a receive conversion stage and a signal-processing circuit connected downstream of the radio frequency component. The signal-processing circuit has an A/D converter and a digital filter. The pass-band of the digital filter is variable. In operation, the pass-band is set according to a selected system standard of the received radio signals.
