Abstract
Two oscillators are utilized to convert digital data into an FSK modulated signal. One oscillator is at the mark frequency and the other is at the space frequency. FSK modulation is accomplished by switching between the two frequencies based on the state of the digital data. Phase and frequency shifting techniques are also provided to insure that a desired difference between the mark frequency and space frequency is maintained and to also insure that a proper phase relationship is maintained between the output from the two oscillators.
