Abstract
The disclosed signal strength adapter circuit includes a signal adapter (20) having a signal input (21) for receiving a signal whose strength is to be adapted, a digital set input (22) for receiving a strength value, and a signal output (23) for producing an adapted signal whose strength corresponds to the strength value on the set input (23). At successive discrete instants, a generator (24) generates a series of function values which determine an exponential time function (30) in coarse steps. The circuit includes an adapter circuit (26, 27) for adapting the signal strength in fine steps in the time intervals between the instants at which the function values are generated.
