H03M 7/3035
With provisions for rendering the modulator inherently stable
Official title: {with provisions for rendering the modulator inherently stable, e.g. by restricting the swing within the loop, by removing part of the zeroes using local feedback loops, by positioning zeroes outside the unit circle causing the modulator to operate in a chaotic regime}
