Noise blanker circuit and method for removing noise and correcting a signal
Abstract:
A noise blanker circuit and method of removing impulse noise from a signal and correcting the signal is provided. The circuit includes a detection stage, a pulse removal stage, and a pulse removal correction stage. The detection stage includes at least an input that emits an input signal along a first signal path and a second signal path. The first and second signal paths are in communication with a blank pulse generator. The pulse removal stage is in communication with the input and includes at least a sample and hold device that samples and holds the input signal based upon an output of the blank pulse generator. The pulse removal correction stage includes at least a pulse removal device in communication with the detection stage and the pulse removal stage and corrects the input received from the pulse removal stage based upon the output of the blank pulse generator.
