PURPOSE:To obtain a characteristic applying a desired clip processing by using an N-bit input value as an output value when the carry of the most significant bit of an adder is logical '1' by an output switch circuit and using a contant '0' of N-bit natural binary notation as the output value when logical '0'. CONSTITUTION:With an input value 10 given to an input terminal 1, the adder 4 adds the input value 10 and a constant output value 30 and the result of sum is given as a carry output 49. When the input value 10 is less than a prescribed value 'k', the carry output 49 is logical '0' and when the input value 10 is 'k', or over, the carry output 49 is logical '1'. That is, when the carry output 49 is logical '0', the output value 60 is used as the constant '0' of natural binary notation and when the carry output 49 is logical '1', the input value 10 is used as the output value 60 so as to obtain a desired input/output characteristic as shown in solid lines 1 in figure. |
