Filed: 1970-02-13
Abstract: 1293223 P.C.M. encoders FUJITSU Ltd 13 Feb 1970 [14 Feb 1969] 7150/70 Heading G4H In a P.C.M. encoder the input signal is rectified, polarity discriminated and the modulus of the signal is encoded, the polarity discrimination being performed during the encoding operation. The signal is polarity discriminated in REC and a sign bit generated, the modulus of the signal then passes to a coding unit having stages S2-S4 where the signal is progressively digitized from the most to the least significant bit. The difference between the digitized portion and the analogue input passes to the next stage in analogue form. Each stage has a logic unit and a memory comprising two "AND" gates and a flip-flop. Control pulses P 1 -P 4  and D 1 -D 4 , Fig. 4 (not shown), ensure that the polarity discrimination is carried out during the encoding operation. In this way errors due to transients are reduced. Final control pulses D1-D4 applied to the "AND" gates just preceding the output "OR" gate ensure that the encoded signal is transmitted in the correct sequence, i.e. with the sign bit first followed by the most significant bit and so on.
