An arrangement for generating an SSB signal.

摘要

An SSB generator in which a digitised analogue signal is processed in accordance with Weaver's method. The baseband I and Q signals are interpolated at a sampling frequency fs in respective first interpolators (30, 32). The interpolated signals are frequency up-converted to an output SSB carrier frequency Nfs by applying said signals to respective second interpolators (38, 40) in which the signals are sampled at 4Nfs. The samples at the outputs of the second interpolators (38, 40) are applied to a multiplexer (42) which provides a digitised version of the SSB signal which is converted to an analogue signal and filtered.
