Abstract
PURPOSE:To enable to simplify the circuit constitution and to make stable the operation, by the code constitution which can simultaneously take the synchronism of frame and the conversion of number of bits. CONSTITUTION:In the constitution of one frame from r sets of words of W1-Wr and the frame synchronizing signal FS, the number of bits p of FS is selected as an integral multiple u of m bits and the number of bits q for one word is similarly selected as an integral multiple v of m bits, then the total number of bits X of one frame is X=p+(rXq)=m(u+rXv). Since the total number of bits for one frame is an integral multiplex of m bits even if the value of the number of words r is any number, the one frame as a result of the conversion to n bits is an integral multiplex of n bits. Accordingly, when the FS of the specified bit pattern is detected 7 from the reproduced PCM signal from the input 1, this can be of frame synchronism and the section in 6 bits of 3-PM system, allowing to operate the 3PM demodulation circuit 2 and the frame synchronizing circuir 4 based on this detection.
