Abstract
The problems of digital interfacing of t.d.m.¿f.d.m. systems are considered. A novel method of converting t.d.m. to f.d.m. signals using digital signal processors is proposed. This method makes use of a periodically varying digital filter coupled with a fast Fourier transformer. The combination of these two devices takes advantage of the lowest possible sampling rate for the system, and thus greatly reduce the complexity and cost of the convertor. The method can be applied equally well for f.d.m. to t.d.m. conversion.
