Abstract:

A phase continuous FSK modulator has been instrumented using digital techniques. The system allows for the selection of operating modes using multi- frequency level operation along with variable signaling rates. The principal feature of this modulation technique is its property of yielding a spectrum with a narrower bandwidth than conventional FSK at a given keying rate.
