1. An apparatus, comprising a compressor blade for a compressor, the blade configured to extend radially from a central hub of the compressor, and comprising:
a pressure surface on one side of the blade and a suction surface on an opposing side of the blade;
wherein the pressure surface and the suction surface extend from a common leading edge of the blade to a suction surface trailing edge and a pressure surface trailing edge, and wherein the trailing edges of the pressure surface and suction surface of the blade are joined by a third trailing edge surface, wherein a portion of the third trailing edge surface of the blade alternates between a first circumferential direction and a second opposing circumferential direction when measured along the radius of the blade, forming an undulating profile having a plurality of peaks and valleys, the plurality of peaks and valleys having non-uniform frequency along the blade.
