| 1. An apparatus, comprising:
a signal conditioning module to receive a baseband signal, said signal conditioning module comprising:
multiple parallel paths for splitting said baseband signal, the multiple parallel paths comprise n paths having gain factors
α1, . . . ,αn, where α1+α2+ . . . +αn =1 and n comprises a positive integer value, the multiple parallel paths comprising a first path wherein the baseband signal
is provided directly to an amplifier;
a delay block for delaying each of the subsequent multiple parallel paths; and
a combiner block to combine said multiple parallel paths to form a conditioned signal having a lower signal amplitude peak-to-average
ratio than said baseband signal.
