A transmission signal pre-processing method and apparatus for out-of-band emission cancellation are disclosed. It also relates to a method of reducing the allegenicity of an animal, using such a cloth. The microcontroller is connected to a power terminal of the chip card for receiving power from a first power supply of the host device. The metal structure is manufactured by thin plate pressing and sufficient strength can be maintained even if the thickness is low. The invention also relates to novel phosphane ligands.
