Abstract: A communication apparatus and a control method thereof adapted to switch environment of a cellular phone are disclosed. The method sets the communication apparatus in a first mode. The first mode automatically switches into a second mode during the execution of the build-in function of the communication apparatus. The build-in function includes receiving/transmitting E-mail, website browsing, photographing and music. The second mode responds to the environment of the execution of the build-in function. By such switching, the execution of the multi-media operation is not interrupted when the communication apparatus receives an electrical message.

Abstract: The present invention discloses a method of constructing the testing procedure of an analog circuit by applying the fault classification tables of the analog circuit. The constructing method classifies the fault classification tables to establish a decision tree. Entropy definitions are defined and the decision tree is thus established by following the rule of decreasing the entropy values. A search procedure of the decision tree can be performed as to find the failure mode next time when the analog circuit is detected.

Abstract: The present invention discloses a method for constructing the fault classification tables of analog circuits, and the fault classification tables can be further applied to construct analog CAT tools. The constructing method uses the fault models but the normal models inserting in parts of the analog circuit components, and then utilizes a circuit simulator to obtain waveform from the defect analog circuit. Exclusive and non-exclusive classification schemes are applied to establish the failure modes of the defect analog circuit when the waveform is recorded as a fault dictionary. It is unnecessary to construct a real analog circuit as the conventional does.
