Abstract
Between a method in which an integer signal code is obtained by using an encoding method based on periodicity and a method in which an integer signal code is obtained using an encoding method which is not based on periodicity using an index indicating a degree of periodicity of a sample sequence in a frequency domain, processing of a first coder is executed only in a method for which the number of bits of the integer signal code is expected to be reduced, and a gain obtained through the processing of the first coder in the method for which the number of bits of the integer signal code is expected to be reduced is utilized in a method for which the number of bits of the integer signal code is not expected to be reduced.
