A BTSC encoder includes dual channel ADC, sync separator, audio processor, filtering device, and a composite audio signal generating device. The filtering device includes a first filter for providing a filtered L+R signal, and a second filter for providing at least one of: i) a filtered and combined pilot and modulated L-R signal and ii) separately filtered pilot and modulated L-R signals. The composite audio signal generating device is responsive to the filtered L+R signal, and at least one of i) the filtered and combined pilot and modulated L-R signal and ii) the separately filtered pilot and modulated L-R signals for generating and outputting a composite analog audio signal. In all embodiments, the modulated L-R signal is filtered via an anti-splatter filter.
