摘要： The disclosed device easily and precisely satisfies a requested output range, and is provided with: a ΔΣ-modulator (12) which converts a digital input signal to a pulse signal; an input comparison device (11) which compares an input value that corresponds to the digital input signal, and a pre-set threshold value; and a thinned output control unit (14) which, when the result of the comparison by the input comparison device (11) shows that the input value is less than the threshold value, reduces the output value corresponding to the input value in accordance with the size of the difference between the input value and the threshold value, and sets the output value to 0 when the input value is 0.
摘要翻译：所公开的装置容易且精确地满足请求的输出范围，并且具有：将数字输入信号转换为脉冲信号的调制器（12）; 比较与数字输入信号对应的输入值和预设阈值的输入比较装置（11）; 以及减量输出控制单元（14），当输入比较装置（11）的比较结果表明输入值小于阈值时，根据该输入值减小对应于输入值的输出值输入值与阈值之差的大小，输入值为0时将输出值设定为0。
