摘要： A digital attenuator is disclosed which is capable of having the output PCM signal attenuated nearly in proportion to the input PCM signal level based upon simple logic operations ofP.sub.out = .alpha. P.sub.in + NwhereP.sub.out = output PCM signalP.sub.in = input PCM signal processed by a compressor.alpha. = a real number satisfying the condition 0 O, to obtain the sum .alpha.P.sub.in + N, the output signal .alpha.P.sub.in, which is obtained in the manner described above, is added to a specific pattern representing N which is generated by a specific pattern generating circuit. The above sum is compared with P.sub.in and when the former is larger than or equal to the latter, P.sub.in becomes P.sub.out, while when the former is less than the latter, the sum is derived as P.sub.out. Thus, an attenuation nearly proportional to the input FCM signal level may be attained.
