In an electronic circuit and method for reducing interference in a measurement signal or signals, wherein the interference comprises a plurality of interference components: (a) There is at least one primary signal processing unit, each having a primary signal processing unit comprising a respective measurement signal input for receiving a respective one of said measurement signal or signals. The or each primary signal processing unit comprises a plurality of interference reduction modules. (b) A respective compensation signal component input is provided for each interference reduction module. (c) A compensation signal processing unit is provided, having a compensation signal input and comprising means for deriving from at least one compensation signal, a plurality of compensation signal components each of which is related to a respective one or more of the interference components. (d) A respective compensation signal component output is connected to a respective one of the compensation signal component inputs.
