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.
