PROBLEM TO BE SOLVED: To provide a linear system coefficient estimation method with high noise resistance, an integrated circuit employing the same, a touch panel system, and an electronic apparatus.SOLUTION: A noise removal unit 101 is disposed which removes noise which is superposed upon N linear sum signals of object coefficients by filtering the linear sum signals. An estimation unit 105 estimates, from a dot product computation of a signal based on the N linear sum signals from which the noise has been removed and N M-dimensional vectors, values of the M object coefficients. |
