Signal processing device, signal processing method, and computer program

A signal processing method, comprising:

• detecting samples, in which values obtained based on a number of times of appearance of bits in a first modulated signal and a second modulated signal coincide with each other over a plurality of samples within a set period,
• wherein the first modulated signal is a ΣΔ modulated input signal that is delayed and the second modulated signal is the ΣΔ modulated input signal that is again subjected to the ΣΔ modulation;
• switching between the first modulated signal and the second modulated signal to output one of the first modulated signal or the second modulated signal;
• and
• controlling the switching between the first modulated signal and the second modulated signal based on the samples in which the values coincide with each other.

A non-transitory computer-readable storage medium having stored thereon, a set of computer-executable instructions for causing an information processing apparatus to execute operations comprising:

• detecting samples, in which values obtained based on a number of times of appearance of bits in a first modulated signal and a second modulated signal coincide with each other over a plurality of samples within a set period,
• wherein the first modulated signal is a ΣΔ modulated input signal that is delayed and the second modulated signal is the ΣΔ modulated input signal that is again subjected to the ΣΔ modulation;
• switching between the first modulated signal and the second modulated signal to output one of the first modulated signal or the second modulated signal;
• and
• controlling the switching between the first modulated signal and the second modulated signal based on the samples in which the values coincide with each other.
