This research introduces a one-bit signal processing structure called the phase amplitude control bit stream adder. The proposed method is a digital filter structure, which is capable of controlling amplitude and phase over a one-bit sine wave without the need of directly multiplying the one-bit stream with a floating-point constant. The method allows performing signal processing in the one-bit domain, thus maintaining high-resolution characteristics associated with one-bit signals. It has applications in precision variable oscillator control and in oscillator bank additive synthesis reconstruction models. The research also explores a method for one-bit oscillator bank synthesis, without using intermediate multi-bit stages directly applied to the signal.
