TA0038 DC ACCURATE FSK MODULATOR

TA0038 A typical, low cost, FSK modulator is implemented by injecting the modulation voltage into the phase lock loop of the carrier synthesizer. This is done in two ways, by summing the modulation voltage and the loop error voltage together and applying that to a VCO tuning port. Or, by using a separate tuning port usually having lower sensitivity to voltage changes. The modulating data would change the carrier frequency by a predetermined amount (deviation). This, .
