Abstract
An electronic apparatus is described. The apparatus includes a circuit element configured to output a signal comprising a modulated frequency component. The apparatus also includes a filter arrangement comprising first, second and third notch filter arrangements, wherein each of the first and second notch filter arrangements comprise a first series inductor, and a series shunt configuration comprising a second inductor and a capacitor coupled in series and the third notch filter arrangement comprises a series inductor and a shunt capacitor, wherein each of the notch filter arrangements are configured to generate a notch in a frequency response to attenuate the output signal at a frequency of the modulated frequency component.
