Abstract
PURPOSE:To naturally execute the connection of a waveform at a connecting point in a comparatively short time, by removing a level difference at the connecting point, and gradually connecting like dalta modulation. CONSTITUTION:A difference of amplitude of two continuous sampling values (n), (n+1), which have been sampled by a sampling period and quantized and PCM- coded in the proximity of an editing connecting point detection control signal, is divided 64, 65 into polarity and absolute value information. Subsequently, an output of the absolute value is made an address of an ROM73, an output of the ROM73 is made a specific function, by which the step DELTA is made variable in accordance with the extend of a level difference, DELTA is added 69 to the sampling value (n) when the polarity is positive, and it is subtracted 68 when it is negative, which is made the sampling value (n+1).
