independent sideband (ISB)

The Independent Sideband Modulation (ISB) is a two sideband mod ulation (ZSB) where each sideband is modulated with a different signal

. This modulation type is available with full and with suppressed carrier signal

. ISBmodulation is implemented using filter techniques by mixing the two signals in two mixers with the same carrier frequency

and then combining them as single sidebands in each case. The advantage lies in the better use of the available frequency band.
