Abstract (en)

[origin: WO9300737A1] A method of direct digital synthesis of linear frequency modulated wave forms comprising the steps of: at a given regular time, adding a fixed frequency increment word (1) to a frequency control value stored in a first register (4) to produce a lineally increasing frequency control word; adding the frequency control word stored in the first register (4) to a second register (8) to form a quadratically increasing phase word; converting the quadratically increasing phase word to an amplitude value using a lookup table stored in a memory means (9) to produce a lineally increasing frequency, and periodically resetting the frequency control word to produce a frequency sawtooth. Also a device for implementing the method being an arbitrary waveform generator comprising a pluraality of accumulators (4+5, 7+8), a memory means (9), a convertor means (10) and a clock means (6).
