Method for adjusting interference radiation of electronic circuit i.e. microprocessor, involves providing inaccurate clock signal to electronic circuit, and operating electronic circuit with inaccurate clock signal

摘要

The method involves controlling a digital oscillator (103) with an inaccurate excitation signal for obtaining an inaccurate clock signal (125), where the excitation signal is provided by an excitation signal providing device (105) having a capacitor that is connected to the oscillator. The inaccurate clock signal is provided to an electronic circuit (101), where the clock signal has a frequency response characteristic that is moved within a predetermined interval based on predetermined vibration properties. The electronic circuit is operated with the inaccurate clock signal. An independent claim is also included for a device for providing an inaccurate clock signal for an electronic circuit.
