Abstract (en)

[origin: WO9957805A1] Apparatus for timing recovery of vestigial sideband (VSB) modulated signals including a narrow band pass filter (28) adapted to receive a baseband VSB signal (26) having a positive-frequency signal edge (30) and providing a portion of the positive-frequency signal edge (30). A non-linear transformer (32) is adapted to receive the signal portion and provide a timing-retrievable signal to a loop filter (34) which is adapted to receive and average the timing-retrievable signal to provide a timing corrected signal.
