DTTB Transmission Spectrum
Notes : 1. Intermod. level increases at double the rate the input level is increasing.
2. Noise level increases at the same rate the input level is increasing.
3. As COFDM is the same as noise, the display of C/N is independent of the resolution B/W.
4. The shape of the sidebands is influenced by the transmitter’s response.
5. Either noise or intermod. may dominate.
