How is direct binary FSK modulation generated?
Pick an answer to check it.
Answer: B. By changing an oscillator's frequency directly with a digital control signal
Direct FSK shifts the oscillator's frequency itself between two values under control of the digital data signal. No audio tones are involved, unlike AFSK.
Tip: Direct FSK: data directly shifts the oscillator.
