As copying machines and other office devices continue to advance in functionality, achieving higher levels of image quality, processing speed, and full-color reproduction, the data processing capacity of their control circuitry also improves year after year. The higher running frequencies of the circuits, however, make it increasingly difficult to achieve stable operations while minimizing noise.

In response, Canon has introduced circuit board design-support techniques, including a transmission line simulation analysis that analyzes the travel times of the electric signals transmitted on printed circuit boards of circuits in a few dozen picoseconds,* as well as an electromagnetic field simulation analysis that estimates the level of electromagnetic noise generated by electric devices at the design stage. These techniques ensure improved operational accuracy at the prototype-testing stage and help to greatly reduce development lead times, while also enabling the quick market introduction of products equipped with the latest functions.
