ABSTRACT:
A symbol detector (110) includes an analog-to-digital converter (115) for converting signal voltages to digital values and peak and valley counters (310, 315) for tracking the digital values to determine peak and valley values associated with high and low voltages of the signal. The symbol detector (110) further includes calculation circuitry (356) for calculating upper, lower, and center thresholds based on the peak and valley values and a decoder (125) for generating data symbols in accordance with the upper, lower, and center thresholds.
