US 2022/0190640 A1 · SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND PROGRAM

Abstract

The present technology relates to a signal processing device, a signal processing method, and a program capable of reducing influence of crosstalk. Provided are: a plurality of comparators; a delay unit adapted to delay output of each of the plurality of comparators; and a subtractor adapted to subtract, from a supplied signal, a signal from the delay unit. The signal processing device processes signals transmitted in N phases and includes (N−1) or more comparators. Each of the plurality of comparators has a different threshold value set and compares a received signal with the threshold value, and in a case where the signal transitions between a plurality of voltage levels, the threshold value is set to a value within adjacent voltage levels. The present technology can be applied to a reception device that receives a signal transmitted in multiple phases and via multiple lines.
