Patent ID: 11824572

Abstract:
A digital filter circuit for processing at least one signal is described. The digital filter circuit includes an input circuit, a first filter sub-circuit, and a second filter sub-circuit. The input circuit is configured to receive at least two real-valued input signals and/or at least one complex-valued input signal. The digital filter circuit has a first configuration that is associated with complex-valued input signals, wherein in the first configuration the first filter sub-circuit is configured to filter a real part of the at least one complex-valued input signal and the second filter sub-circuit is configured to filter an imaginary part of the at least one complex-valued input signal. The digital filter circuit has a second configuration that is associated with real-valued input signals, wherein in the second configuration the first filter sub-circuit and the second filter sub-circuit are configured to filter the at least two real-valued input signals in parallel and/or wherein the first filter sub-circuit and the second filter sub-circuit are configured to jointly filter at least one of the at least two real-valued input signals with increased parallelism. Further, a measurement instrument and a signal processing method are described.
