WebThe resulting speech enciphering system, called SYGSALY, became the first working example of PCM technology. Under the cloak of secrecy, Bell Labs made great strides in advancing the state-of-the-art in PCM techniques. By the war's end, several groups at Bell Labs had worked on PCM. SIGSALY terminal (1943) WebQ.1. How is the ‘information’ transmitted in a PCM system? Ans. In PCM, the ‘information’ is transmitted in the form of ‘code words’. The amplitude, width and position of the pulses at the PCM transmitter output are always constant. Q.2. What is quantization? Ans. It is the process of approximation.
