Abstract
A touch panel controller (A) includes: a capacitor drive portion (A); a multiplying portion (A) which performs multiplication of first linear sum signals by a second code sequence to obtain signals and then performs addition of the signals to generate a second linear sum signal; an inner product operation portion (A) which generates a first inner product operation signal by calculating an inner product of the second linear sum signal and the second code sequence; an inner product operation portion (AA) which generates a second inner product operation signal by calculating an inner product of the first inner product operation signal and the first code sequence. This makes it possible to reduce a mounting area of the touch panel controller.
