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 - 120 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. Author
