ABSTRACT:
An equalization circuit adjusts (e.g., equalizes) an input signal according to the value of one or more adjustment signals (e.g., equalization coefficients) without a multiplication operation. For example, the circuit may add or subtract a value of a coefficient signal to the amplitude of an input signal. Here, whether the coefficient is added or subtracted may depend on the sign of a control signal.
