Abstract:
An apparatus for correcting asymmetric waveforms, said apparatus comprising:an input arrangement which accepts an input signal, the input signal having an associated waveform; a splitting arrangement which splits the input signal into at least two paths; a first altering arrangement, associated with a first of said two signal paths, which alters a first portion of the split signal; a second altering arrangement, associated with a second of said two signal paths, which alters a second portion of the split signal; and an output arrangement which recombines the altered split signals into an output signal; whereby the output signal exhibits a substantially symmetric waveform; said splitting arrangement further being adapted to split the input signal into a third signal path; said apparatus further comprising a delaying arrangement, associated with the third signal path, which applies a delay to a third portion of the split signal.
