A laser alignment system is provided for a mechanized irrigation system with the laser alignment system being operatively connected to the drive tower motors of the irrigation system to maintain the spans of the irrigation system in alignment. A processor includes an intelligent DMA controller, which loads a line description that corresponds to a shape or line. The lighting member may be a continuous strip of material, such as an electroluminescent laminate. A transmission low-pass filter of the RF transmitter suppresses noise due to DA conversion, which is contained in I and Q transmission analog baseband signals. In this manner, some column or row circuits are decoupled from the pixel in favor of other column or row circuits.
