Abstract
A digital chirp generator for generating linear frequency modulated signals, comprises a plurality of frequency/phase accumulators pipelined together. Each frequency/phase accumulator includes a frequency accumulator driving phase accumulator. In the pipelined configuration the frequency accumulator and the phase accumulator of each frequency/phase accumulator are interconnected with the corresponding frequency accumulator and phase accumulator adjacent of the frequency/phase accumulator.
Claims19
A digital chirp generator comprising:
- a plurality of successively adjacent frequency/phase accumulators,
- each of said frequency/phase accumulators including a frequency accumulator means and a respective phase accumulator means driven by the respective frequency accumulator means,
- said plurality of frequency/phase accumulators being pipelined together including:
- each frequency accumulator means being pipelined to the frequency accumulator means in the next adjacent frequency/phase accumulator and
- each phase accumulator means being pipelined to the phase accumulator means in the next adjacent frequency/phase accumulator.
