Abstract:
A very low intermediate frequency (VLIF) receiver comprising a first and second mixer circuits, characterised in that receiver comprises a means of estimating the energy in a desired signal band; a means of estimating the energy in a band of frequencies comprising the desired signal band; and a means of altering a VLIF of the receiver according to the ratio of the energy in a desired signal band and the energy in the band of frequencies comprising the desired signal band.
