<p>An adaptive digital hysteresis technique where two modes are used to develop the output value, rather than the conventional single rounding technique, to reduce the quantization errors. To determine which of two different schemes, referred to as floor and ceil, to use, there are trip points to select modes. The floor and ceiling trip points are developed based on the value of the input signal. When the trip point for the other mode is exceeded and the next trip point for the current mode is not exceeded, the mode is changed. The output values of the technique have a lower error than the prior art rounding with hysteresis techniques. <IMAGE></p> |
