The article focuses on dithering in mixed signals. When a triangular dither with peak-to-peak amplitude of atleast one least significant bit (LSB) is added to a signal, the average of quantized signal becomes equal to the original signal value. Mixing two frequencies into analog-to-digital converter's (ADC) filter provides inexpensive source of dither. One type of dithering allows higher frequency dither with just single dither register in all digital-to-analog converters (DACs).
