A frequency translation from baseband or RF to more easily filter, distribute, modulate and demodulate the signal. |
Carrier-based technologies must modulate and demodulate a complex analog carrier waveform, and incorporate the componentry required to do so. |
Compatible with constant coding and modulation, variable coding and modulation and ACM modes, Syper can demodulate all constellations with bit-rates up to 170Mbps. |
In the case of one Mobile TV channel being transmitted on the central segment, the receiver has to decode the signal and demodulate this segment of the OFDM signal. |
Devices performing a similar function to that of a modem but which do not modulate and demodulate signals are not considered to be modems. |
That would be pointless, however, as an attacker would not have any way to demodulate the data. |
