A communication terminal is provided having a signal reception path which has a bandwidth widening device for artificially widening the bandwidth of a received signal in the communication terminal, a digital/analog converter and a loudspeaker, and includes a signal transmission path, which has a microphone, a transmission path low-pass filter and an analog/digital converter, in which case an echo compensation device is provided between one output of the bandwidth widening device and a connecting point of the signal transmission path, beyond the analog/digital converter with respect to the microphone, and further provides a method for artificially widening the bandwidth of a received signal in a communication terminal.
