Abstract: Mixing N information-time signals. The time signals are each converted into the frequency domain, into one of N complex information signals where N is an integer greater than 1. Spectral values of the N complex information signals which match in a frequency are each converted into a first and a second component. The N first components of the N frequency-matching spectral values are combined into a first combination component. The N second components of the N frequency-matching spectral values are combined into a second combination component. The first and second combination components are combined into a result spectral value. The above steps are also performed for other frequency-matching spectral values of the N complex information signals for generating other result spectral values. The result spectral values thus obtained are combined into a complex output information signal.
