    • Abstract


      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.

    • Continuous Article Publication

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
