Abstract
A modulated signal is translated to a broadcast frequency by a translation phase lock loop. In the translation phase lock loop the output frequency, which is the broadcast frequency, is mixed with a translation frequency, and the resulting translated frequency is compared to the modulated signal. If an amplitude modulator is inserted into the translation loop, the phase comparison/feedback nature of the phase lock loop will tend to cancel the phase noise introduced in the amplitude modulation process. Any other circuits placed within the loop will tend to have any phase noise they introduce, which is in the phase lock loop bandwidth, canceled by the loop.
