Abstract:
1. Apparatus arranged to generate a plurality of radio-frequency RF subcarrier signals for transmission in a frequency range between two adjacent ultra-high frequency UHF broadcast channels, the apparatus comprising: a signal generator arranged to generate a plurality of local oscillator LO signals based on a reference frequency; and a plurality of mixers each arranged to mix one of the LO signals with one of a plurality of input signals to generate one of the RF subcarrier signals, said input signal including information to be transmitted by said RF subcarrier signal, wherein the signal generator comprises a plurality of signal generation modules each arranged to receive the reference frequency and generate one of the plurality of LO signals at a different frequency, wherein the plurality of input signals are arranged to have the same frequency as each other, and wherein the plurality of signal generator modules includes:
