Measuring device and method
First Claim
1. A measuring device for processing an input measurement signal, the measuring device comprising:
- a receiver configured to receive the input measurement signal to generate a digital measurement signal; and
a digital processor including;
a transformer configured to transform the digital measurement signal into a processed measurement signal in a frequency domain, anda subtractor configured to subtract a first sideband of the processed measurement signal in the frequency domain from a second sideband of the processed measurement signal in the frequency domain to generate a residual signal,wherein the subtractor is further configured to detect a strongest carrier present in the processed measurement signal,wherein the first and second sidebands of the processed measurement signal are separated by the strongest carrier present in the processed measurement signal, andwherein the receiver is further configured to process the input measurement signal only by linear operations before it digitises the input measurement signal to form the digital measurement signal.

Abstract
A measuring device serves for the detection of a simultaneous presence of at least a first signal and a second signal in a measurement signal. The measuring device contains a receiver for receiving the measurement signal as a digital measurement signal and a processor. This processor includes a transformer for transforming the digital measurement signal into a measurement signal in the frequency domain. The processor further contains a subtractor for subtracting the first sideband of the measurement signal in the frequency domain from a second sideband of the measurement signal in the frequency domain. In this context, the subtractor generates a residual signal.
