Abstract

A system such as a mechanically tuned radio can have a signal path to receive and process an incoming radio frequency (RF) signal and to provide the processed signal to a first analog-to-digital converter (ADC) to convert the processed signal to a digital signal and to digitally demodulate the digital signal to obtain an audio signal, where this first ADC is separate from an auxiliary ADC not part of the signal path.
