Device for supplying power to an electronic signal processing stage

摘要

The invention relates to a device (8) for supplying power to an electronic signal processing stage (7). Such signal processing stages are used in active and passive sensors such as pulse-operated separation sensors or video receivers. In order to reduce the power consumption of the signal processing stage, it is proposed according to the invention that the device (8) for supplying power be connected in a controlled manner essentially only when signals to be processed are present. As a result of this measure, even signal processing stages having complex signal processing can be supplied with a small amount of power, which can be applied, for example, by a battery. <IMAGE>
