Abstract
The spectrum of Nyquist-rate, single-bit quantized, randomly-dithered, amplitude-modulated, sinewave is studied analytically. It is shown that by choosing the dithering sequence appropriately and imposing certain constraints on the modulating sequence, the output is spurs-free and the quantization noise is white. MATLAB simulation confirms the theoretical results.
