摘要： The present invention is concerned with a method and an arrangement relating to visual display units, preferably a picture tube (1), for reducing to a minimum the electrical alternating fields generated by the display unit in the unit surroundings. The visual display unit is provided with a voltage connected part (5) on which undesirable voltage variations occur. These voltage variations are indicated. A signal which is phase inverted in relation to the indicated voltage variations is generated. The generated phase-inverted signal is fed back to the voltage connected part (5), to compensate for the voltage variations.

摘要： A control unit supplies a new control value to a frequency source. The value is determined by the frequency source frequency and the reference frequency. The control unit further calculates a rate of change value based at least on the new and a previous control value if there is communication with the reference frequency generator and stores these values in corresponding stores. Another control unit calculates a new control value based on the rate of change value from the rate of change store and the last used control value from the control value store and supplies the new control value to the frequency source if there is no communication with the reference generator.
