Title: DETECTION OF SIMULTANEOUS DOUBLE TRANSMISSION
Abstract:
The invention relates to a measuring instrument that serves for detection of the simultaneous presence of at least one first signal and one second signal in a measurement signal. The measuring instrument contains a receiving device for receiving the measurement signal as a digital measurement signal (53) and a processing device (7). To this end the processing device (7) has a transforming device (70) for transforming the digital measurement signal (53) into a measurement signal in the frequency range (54). Furthermore the processing device (7) contains a subtraction device (71) for subtracting a first sideband of the measurement signal in the frequency range (54) from a second sideband of the measurement signal in the frequency range (54). The subtraction device (71) generates a residual signal (55).
