A method for transmitting an analog datastream includes coding data input into a data input device. The resulting coded data is assembled into coded data blocks. These blocks are transformed into at least one discrete multitone symbol. An initial filter value extracted from the discrete multitone symbol is forwarded to a stored-value determining device, to which a frame alignment signal has been applied. A stored value for a first filtering device is determined as a function of the at least one initial filter value and the frame alignment signal. This value, and the multitone symbol, are applied to the first filtering device, thereby generating a filtered discrete multitone symbol. The filtered symbol is forwarded to a second filtering device to which the stored value determined in the stored-value determining device is applied, thereby generating a transient-compensated discrete multitone symbol. This is then converted into an analog signal for transmission.
