Abstract:
1. A device, comprising: one or more of at least one amplification element and at least one attenuation element connected in a cascaded manner; a detector respectively associated with each of the one or more of the at least one amplification element and the at least one attenuation element, configured to measure a signal level of a signal at an input of the respective amplification or attenuation element; and a control unit respectively associated with each of the one or more of at the least one amplification element and the at least one attenuation element, each configured to determine a gain or attenuation factor for the respective amplification or attenuation element; wherein each control unit comprises a multiplier and an adder disposed in series with the multiplier, wherein the multiplier and the adder are configured to apply a weighting factor and an offset value, respectively, to the measured signal level of the signal at the input of the respective amplification or attenuation element, and wherein the weighting factor and the offset value applied to the measured signal level of the signal at the input of the respective amplification or attenuation element are stored in a buffer, and are addressed within the buffer based on the signal level measured by the respective detector.
