Abstract
A signal processing circuit for a measurement instrument is described. The signal processing circuit includes an analysis circuit, a measurement input, and at least two parallel measurement channels. The parallel measurement channels are configured to process the input signal, thereby generating first and second complex-valued measurement signals. The analysis circuit is configured to determine first and second error quantities associated with the first and second complex-valued measurement signals, respectively. The analysis circuit is configured to determine a complex-valued average signal corresponding to a combined average of the first and second complex-valued measurement signals. The analysis circuit is configured to determine a combined error quantity based on the complex-valued average signal. The analysis circuit is configured to determine a comparison quantity based on the combined error quantity as well as based on the first error quantity and/or the second error quantity.
