ABSTRACT:
Systems and techniques to configure a read channel include, in at least one implementation, an apparatus including: detection circuitry configured to process an input signal from a machine-readable medium to calculate metrics; monitoring circuitry configured to determine a polarity of the input signal based on the metrics and at least one of multiple framings of signal samples of the input signal; and selection circuitry to configure a read channel for the machine-readable medium based on the determined polarity.
