Abstract
A signal receiver may include a limiter and an amplifier that is connected to the limiter. The limiter may receive an input signal, generate a limited signal using the input signal, limit values of the limited signal in a first range, and output the limited signal. The amplifier may receive the limited signal, generate an output signal using the limited signal, and output the output signal, wherein values of the output signal are in a second range, and wherein the second range is larger than or equal to the first range.
