  • Codec circuit and method for increasing the data transmission rate during a modem transmission
    Patent number: 6658097
    Abstract: Codec circuit for increasing the data transmission rate in a modem transmission with a first programmable digital filter (13) which is connected into a transmission signal path of the Codec circuit, a second programmable digital filter (22) which is connected into a reception signal path of the Codec circuit, a modem signal detection device (31) for detecting whether the transmission signal which is output on the transmission signal path or the reception signal which is received on the reception signal path is a modem signal, the modem signal detection device (31) switching the first and second digital filters (13, 22) to a widened filter bandwidth when a modem signal is detected.
