METHOD FOR CONTROLLING THE MODE OF AN ELECTRONIC APPLICATION

摘要

Method for controlling the mode of an electronic application like audio systems, display systems or portable equipment. The output stage of the electronic application controls the modes of the system, for example a normal mode, a standby mode or a sleep mode. The inventive method uses the existing connections for the input signals of the output stage. The allover level of the input signal or signals is divided into several ranges. One of the ranges is the normal operation range and the others who lay above or under the normal range are the extended ranges. The different ranges can be of different levels. The input signal can be a time, frequency, current or voltage. The inventive electronic application can be configured as a single-ended input, as a differential input or as a multiple input.
