  • Arrangement for generating an SSB signal
    Patent number: 4974236
    Abstract: An SSB generator in which a digitized analogue signal is processed in accordance with Weaver's method. The baseband I and Q signals are interpolated at a sampling frequency f.sub.s in respective first interpolators (30, 32). The interpolated signals are frequency up-converted to an output SSB carrier frequency Nf.sub.s by applying said signals to respective second interpolators (38, 40) in which the signals are sampled at 4Nf.sub.s. The samples at the outputs of the second interpolators (38, 40) are applied to a multiplexer (42) which provides a digitized version of the SSB signal which is converted to an analogue signal and filtered.
