Abstract
A weighting filter is provided for use in a device for transmitting and/or receiving an analog signal. The device is capable of transmitting and/or receiving the analog signal in a predetermined frequency band consisting of two adjacent sub-bands, referred to as first and second sub-bands. The weighting filter includes: a first branch, which attenuates the analog signal; a second branch that filters the analog signal and has a bandwidth corresponding to the first sub-band or to the second sub-band; and a module that combines signals from the first and second branches.
Claims12
A weighting filter intended for use in a device for transmitting and/or receiving an analog signal,
- said device being capable of at least one of transmitting or receiving said analog signal in a predetermined frequency band formed by two adjacent sub-bands called first and second sub-bands,
- wherein said weighting filter comprises:
- a first branch configured to attenuate the analog signal comprising the first and second sub-bands;
- a second branch configured to filter the analog signal comprising the first and second sub-bands, said second branch having a bandwidth corresponding to said first sub-band or else to said second sub-band;
- and
- means for combining signals coming from the first and second branches.
A device configured for transmitting an analog signal in a predetermined frequency band formed by two adjacent sub-bands, called a first sub-band and a second sub-band, wherein the device comprises:
- one weighting filter, which comprises:
- a first branch configured to attenuate the analog signal comprising the first and second sub-bands;
- a second branch configured to filter the analog signal comprising the first and second sub-bands, said second branch having a bandwidth corresponding to said first sub-band or else to said second sub-band;
- and
- means for combining signals coming from the first and second branches.
A device configured for receiving an analog signal in a predetermined frequency band formed by two adjacent sub-bands, called a first sub-band and a second sub-band, wherein the device comprises:
- one weighting filter, which comprises:
- a first branch configured to attenuate the analog signal comprising the first and second sub-bands;
- a second branch configured to filter the analog signal comprising the first and second sub-bands, said second branch having a bandwidth corresponding to said first sub-band or else to said second sub-band;
- and
- means for combining signals coming from the first and second branches.
A method comprising:
- performing at least one of transmitting or receiving an analog signal in a predetermined frequency band formed by two adjacent sub-bands called first and second sub-bands, and
- weighted filtering said analog signal, implementing one weighting filter comprising:
- a first branch configured to attenuate the analog signal comprising the first and second sub-bands;
- a second branch configured to filter the analog signal comprising the first and second sub-bands, said second branch having a bandwidth corresponding to said first sub-band or else to said second sub-band;
- and
- means for combining signals coming from the first and second branches.
A non-transitory computer readable medium comprising computer program stored thereon and comprising instructions to implement a method of transmitting or receiving an analog signal in a predetermined frequency band formed by two adjacent sub-bands called first and second sub-bands, when said program is executed by a processor, wherein the method comprises:
- weighted filtering said analog signal, implementing one weighting filter comprising:
- a first branch configured to attenuate the analog signal comprising the first and second sub-bands;
- a second branch configured to filter the analog signal comprising the first and second sub-bands, said second branch having a bandwidth corresponding to said first sub-band or else to said second sub-band;
- and
- wherein signals coming from the first and second branches are combined.
