摘要
PROBLEM TO BE SOLVED: To provide a peak clipping circuit that is configured with a small-scale hardware without the need for a multiplier. ;SOLUTION: A clipping level generating circuit 10 generates clipping level data, and a sign inversion circuit 11 inverts the sign of the data. A 1st comparator circuit 12 compares sample data of an I signal with clipping level data and with output data from the sign inversion circuit 11. A 1st selection circuit 13 provides an output of the sample data without modifications, when the sample data of the I signal are more than the output data from the sign inversion circuit 11 and less than the clipping level data, and provides an output of the output data from the sign inversion circuit 11 or the clipping level data in other cases. A 2nd comparator circuit 14 and a 2nd selection circuit 15 conduct processings similar to above on a Q signal.;COPYRIGHT: (C)1998,JPO
