摘要：

We discuss here the design details of an inexpensive programmable Sweeping Local Oscillator System (SLOS) built for use in a 'swept frequency dedispersion scheme' for pulsar observations. A useful extension of the basic Divide-and-Add algorithm for frequency synthesis is developed for this purpose. An SLOS based on this design has been built and used for high time-resolution observations of pulsars at low radio-frequencies.
