Digital exciter having pilot signal compensation |
摘要 |
A digital exciter is presented herein for use in RF broadcasting and wherein the exciter employs pilot signal compensation. This includes an input digital circuit for receiving a modulated digital data at an input sample rate for RF broadcasting at a desired RF frequency. The pilot frequency may be displaced from a desired location at the frequency band because of an error in the input sample rate. A digital compensator determines whether the pilot frequency is displaced and provides a digital correction signal in accordance therewith. A digital correction circuit corrects the pilot frequency in accordance with the correction signal.
