Abstract :
It is shown that a zero-crossing estimator (ZCE), based on sinusoidal interpolation and realised with digital circuitry, can be used in place of a conventional DAC in signal generation of narrowband digital angle-modulated signals. An example of generating a GTFM signal with this ZCE is described.
