The relations between the distortion caused by the action of analog level compressor and its recovery time, compression ratio, type of control circuit and the nature of control element are discussed. It becomes clear that the amount of the distortion strongly depends upon the recovery time of control. The results of calculations, when the attack time of control is supposed zero, give good approximations to the 3rd harmonic distortion measured. When compression is low, the distortions over the 5th harmonic, which are calculated under the supposed condition that the attack time is zero, have some difference from measured values. On the other hand, in the case of high compression, the calculated results become to give good approximation even at higher harmonics. When the actual recovery time is the same, the 3rd harmonic distortion is slightly affected by the type of control circuit, the nature of control element and compression ratio, but the distortion over the 5th harmonic is more affected by these conditions.
