Receiver

A method for receiving an analog signal comprising a frequency band to be digitalized, comprising:

• dividing the frequency band to be digitalized into at least two sub-bands by means of a filter unit comprising at least two filters for at least two receive paths, wherein the at least two filters are coupled to a common signal source in order to acquire the analog signal comprising the frequency band to be digitalized;
• digitalizing, per receive path, the signals of the at least two sub-bands by means of an analog-to-digital converter per receive path;
• and
• merging the at least two digitalized signals by means of digital signal processing coupled to the at least two analog-to-digital converters of the at least two receive paths in order to acquire the at least two digitalized signals,
• wherein the at least two filters, with regard to their filter characteristics, are implemented such that the sub-bands comprise a mutual relative bandwidth of smaller than 1:2 so that the two filters are implemented with a change in filter bandwidth relative to the bandwidth of a neighboring filter of the at least two filters.

A non-transitory digital storage medium having stored thereon a computer program for performing a method for receiving an analog signal comprising a frequency band to be digitalized, comprising:

• dividing the frequency band to be digitalized into at least two sub-bands by means of a filter unit comprising at least two filters for at least two receive paths, wherein the at least two filters are coupled to a common signal source in order to acquire the analog signal comprising the frequency band to be digitalized;
• digitalizing, per receive path, the signals of the at least two sub-bands by means of an analog-to-digital converter per receive path;
• and
• merging the at least two digitalized signals by means of digital signal processing coupled to the at least two analog-to-digital converters of the at least two receive paths in order to acquire the at least two digitalized signals,
• wherein the at least two filters, with regard to their filter characteristics, are implemented such that the sub-bands comprise a mutual relative bandwidth of smaller than 1:2 so that the two filters are implemented with a change in filter bandwidth relative to the bandwidth of a neighboring filter of the at least two filters,
• when the program runs on a computer.
