Abstract :
A circuit comprising a digital memory and a d.a. convertor constitutes a cost-effective method of generating data-window waveforms having optimal frequency-domain equiripple sidelobes. 8-bit quantisation in the memory and harmonic distortion in the d.a. convertor limit the achievable peak/sidelobe ratio to about 51 dB for the near-in sidelobc, and 54 dB for the far-out sidelobes.
