Abstract
A signal processing device includes a first adjuster, a second adjuster, and a digitizer. The first adjuster coarsely adjusts an output range of a signal input to the first adjuster to output a first signal. The second adjuster adjusts an output range of a signal more finely than the first adjuster adjusts to output a second signal. The digitizer digitizes the first signal or the second signal to output a digital signal. The digital signal has an output range of a signal that is finely adjusted with the second adjuster after being coarsely adjusted with the first adjuster.
