    Abstract

    Analogue filters are widely used in active noise control. Usually, their implementation is fixed. Parameters can be varied only by changing components or adjusting their values manually. However, during development of a control system, parameter adjustments are often needed. To address this problem, we have developed an analogue filter bank with an adjustable, digital real-time control of the parameters. The filter has been tested with an existing active noise control application. The structure of the analogue filter is described and results of the tests are given.
