Vehicle radio interference reduction system has equipment clock frequencies adjusted by feedback from high frequency receiver to minimise passband interference

摘要

A vehicle radio interference reduction system has digital equipment or DC/DC converter (1) with clock frequency (f1) changed (f1O) in response to an interference alarm signal (6) fed back over a digital bus communication system (3) from a high frequency receiver (2) to the controller (4) so as to minimise the interference (5) in the receiver pass band (f2, Df2).
