MINIMUM SIGNAL TO NOISE-DENSITY RATIOS FOR TRANSMISSION OF TELETYPE AND SPEECH,
Abstract
The signal-to-noise requirements of a phase modulation communication channel are considered for the transmission of teletype and voice for certain specified performance criteria. Three typical communication services are analyzed: 100 wpm teletype - 1/20 letter error rate; 3 kc voice - 80% word intelligibility, and 3 kc voice - 30 db output baseband signal-tonoise ratio. The transmission requirements are expressed in terms of the minimum signal-tonoise-density ratio required in the pre-detection bandwidth of the signal demodulator. The results are summarized.
