    摘要: A signal generator (1) produces a spread-spectrum bandwidth signal in the frequency range 40 to 90KHz for use in a domestic mainsborne signalling system, In the generator, sixteen individual frequencies, equi-spaced in that range, pass to samplers (5) operating at a clock frequency of 204.8KHz and then to quantisers (6) before storage. The resultant signals are then assembled in appropriate manner by selector switch (9) before being filtered when (temporarily) in the frequency domain.
    The resultant signals duly reach catalogue store (17), where output can be used for programming an EPROM in a mainsborne interface unit.
