ABSTRACT:
A signal filtering apparatus and associated methods enable noise to be significantly reduced or eliminated from a signal. In a described embodiment, the signal is indicative of tension in a slickline. An adaptive filter is used to effectively cancel the noise from the signal, using an input signal characteristic of a noise source.
