The invention creates a method for transmitting an analog data stream in which secondary minima are prevented during an equalization of the analog data stream at the receiving end when approximating the channel transfer function of a transmission channel, wherein the analog data stream is received via the transmission channel, the received analog data stream is converted into a digital data stream in an analog/digital converter, the digital data stream is decimated in a decimation device in order to obtain a decimated digital data stream, a control signal is derived from either the digital data stream or the decimated digital data stream in accordance with a predeterminable adjustment of a switching device, the derived control signal is supplied to a coefficient determining device and wherein equalization coefficients are provided, together with an information item provided by the reference signal, for the equalizer for equalization of the decimated digital data stream in the time domain in the coefficient determining device via the channel transfer function of the transmission channel.
