In one aspect, embodiments of the present invention provide a filter having a first structural member extending along and clockwise about an axis, a second structural member extending along and counter clockwise about the axis and a material capture structure extending between the first and the second structural members and across the axis. The first and second configured pair of transistors may be inductively loaded. Signal adaptive noise decisions can be made both in time and frequency dimensions. The offset voltage feeds back through a summing node to the electrical signal thereby restoring the video signal to the desired DC voltage level with respect to ground. The systems and methods advance the electrodes a second time to form, when the energy is transmitted, a second pattern of lesions either rotationally or axially or both rotationally and axially shifted from the first pattern of lesions.
