Digital signal attenuation circuit for a compact disc-interactive player

A digital signal attenuation circuit for a compact disc-interactive player, comprising:

• a 1/6 divider for dividing by 6 an attenuation control signal inputted from a controller and outputting a quotient signal and a remainder signal as a result;
• a first attenuator for attenuating a digital audio signal which is decoded from an adaptive differential pulse code modulation audio data signal obtained from a compact disc by -1 dB within the range of 0 to -5 dB in accordance with said remainder signal from said 1/6 divider;
• and
• a second attenuator for attenuating an output signal of said first attenuator by -6 dB within the range of 0 to -96 dB in accordance with said quotient signal from said 1/6 divider;
• wherein said 1/6 divider comprises first to fifth dividing sections, each of said dividing sections having the same construction with one another and dividing by 6 a 4-bit input signal;
• and
• wherein one bit of "0" level and 3 higher bits of said attenuation control signal from said controller are inputted to said first dividing section, 3-bit remainder signals from said first to fourth dividing sections and 4 lower bits of said attenuation control signal are respectively inputted to said second to fifth dividing sections in due order, a 3-bit remainder signal from said fifth dividing section is inputted to said first attenuator, and a 5-bit quotient signal from said first to fifth dividing sections is inputted to said second attenuator.
