Because of the extremely accurate amplitude and phase balance that mus
t be maintained within a feedforward amplifier subsystem to achieve th
e necessary cancellation, the amplifier is very susceptible to various
types of environmental disturbances. For this reason, some form of ad
aptive control system must be used to keep the system optimally balanc
ed. This article presents an overview of this control system, along wi
th the microcontroller optimization routine.
