The pre-emphasised signals for the left and right channels are then processed through two low-pass filter (LPF) stages, which roll off the response above 15kHz. This rolloff is necessary to restrict the bandwidth of the FM signal and is the same frequency limit used by commercial broadcast FM transmitters.
