An attenuator control method of a signal processing chain comprising two or more signal processing units, wherein: one of the two or more signal processing units is a signal attenuator adapted to apply adaptive signal attenuation of an attenuator input signal based on one or more attenuation parameters to provide an attenuator output signal, and at least one of the two or more signal processing units has an associated wearout process and a corresponding wearout budget, wherein a wearout event of the wearout process occurs when a level of a wearout indication signal of the signal processing chain is in a wearout region, and wherein the wearout process is modeled by a wearout event cost associated with a corresponding wearout event, the method comprising: obtaining (105a, 106b, 108b, 112b) an indication of whether a wearout event of the wearout process has occurred; if the obtained indication shows that a wearout event of the wearout process has occurred: updating (114a, 114b) a wearout accumulation metric of the wearout process by the associated wearout event cost; comparing (116a, 116b) the wearout accumulation metric of the wearout process with one or more wearout thresholds of the wearout process; adapting (118a, 118b) the attenuation parameters of the signal attenuator based on the comparison; and controlling (120a, 120b) the signal attenuator based on the attenuation parameters. one of the two or more signal processing units is a signal attenuator adapted to apply adaptive signal attenuation of an attenuator input signal based on one or more attenuation parameters to provide an attenuator output signal, and at least one of the two or more signal processing units has an associated wearout process and a corresponding wearout budget, wherein a wearout event of the wearout process occurs when a level of a wearout indication signal of the signal processing chain is in a wearout region, and wherein the wearout process is modeled by a wearout event cost associated with a corresponding wearout event, the method comprising: obtaining (105a, 106b, 108b, 112b) an indication of whether a wearout event of the wearout process has occurred; if the obtained indication shows that a wearout event of the wearout process has occurred: updating (114a, 114b) a wearout accumulation metric of the wearout process by the associated wearout event cost; comparing (116a, 116b) the wearout accumulation metric of the wearout process with one or more wearout thresholds of the wearout process; adapting (118a, 118b) the attenuation parameters of the signal attenuator based on the comparison; and controlling (120a, 120b) the signal attenuator based on the attenuation parameters. obtaining (105a, 106b, 108b, 112b) an indication of whether a wearout event of the wearout process has occurred; if the obtained indication shows that a wearout event of the wearout process has occurred: updating (114a, 114b) a wearout accumulation metric of the wearout process by the associated wearout event cost; comparing (116a, 116b) the wearout accumulation metric of the wearout process with one or more wearout thresholds of the wearout process; adapting (118a, 118b) the attenuation parameters of the signal attenuator based on the comparison; and updating (114a, 114b) a wearout accumulation metric of the wearout process by the associated wearout event cost; comparing (116a, 116b) the wearout accumulation metric of the wearout process with one or more wearout thresholds of the wearout process; adapting (118a, 118b) the attenuation parameters of the signal attenuator based on the comparison; and controlling (120a, 120b) the signal attenuator based on the attenuation parameters.
