Abstract
According to one aspect of the invention, an apparatus is provided which includes one or more analog components, an analog to digital (A/D) converter, and a spectral compensator. The operational characteristics of the one or more analog components have variations based on input signal frequency. The one or more analog components perform their corresponding operations with respect to an input analog signal to generate an output analog signal. The analog to digital (A/D) converter is coupled to receive the output analog signal from the one or more analog components and to convert the output analog signal to a digital signal. The spectral compensator is coupled to receive the digital signal generated by the A/D converter and to compensate spectral characteristics of the digital signal based on variations in the operational characteristics of the one or more analog components.
