Abstract :
The paper describes an AM and FM calibrator which produces AM and FM with a traceable accuracy and which can thus be used as a modulation standard. A PROM is used to store binary sequences which when filtered produce audio waveforms with precisely known characteristics. Using digital techniques, this PROM sequence can amplitude modulate or frequency modulate a carrier, resulting in AM or FM with a precisely known modulation depth or frequency deviation.
