Abstract

Embodiments of the present invention may provide a signal processing circuit that may comprises an analog-to-digital converter (ADC), and an output restriction circuit. The output restriction circuit may reduce the accuracy of the digital output of the ADC when signal content exceeds a pre-determined spectrum mask in an undesirable band. In one embodiment, the input signal spectrum may be actively monitored and when the input spectrum is inconsistent with an intended application, the output resolution may be restricted, for example, by truncating least significant bits (LSBs) of the digital output or adding digital noise.
