Abstract
PURPOSE:To give the zero crossing wave distortion corrective function to the decoder, by adding the means supplying the level corresponding to uni-quantized step having the same polarity as either one of polarity bit information to the output. CONSTITUTION:To the two selective contacts selected by the output of the switch circuit B1, the constant current source I in reverse direction is respectively connected. To this selective contact, the switch circuits B2-B4 providing the common contact connected with the pulse code from the input terminal are located. The common contact of the switch circuits B2-B4 is led to the output terminal OUT via the resistor connected to the ladder shaped circuit network. To the output terminal OUT, the zero crossing wave distortion correction circuit 1 providing the positive polarity constant current source of I/4 in current value is connected. The switch of the zero crossing wave correction circuit 1 is closed with the positive output of the switch 4 circuit B1, and the correction of zero crossing distortion can simply be made by only adding this circuit 1.
