Weighting filter, and corresponding methods and devices for transmitting and receiving an analog signal and computer program

摘要

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.

主权项

1. 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.
