B. Priestley, G. A. Warwick, A.J. Prescott, William D. Gosling · Radio and Electronic Engineer · 1980
An unusual class of digital frequency synthesizers is presented capable of very high frequency-resolution. Construction may be made very simple. In typical applications the complexity of the hardware may be reduced by up to 50% compared with earlier approaches. A standard circuit is defined which may be used in a variety of applications, several of which have been outlined as illustrations of the flexibility of the technique.
