Abstract: An apparatus for generating a broadcast television stereo signal has a left channel and a right channel. An analog-to-digital converter converts the right-channel signal to a right digital signal and the left-channel to a left digital signal. A circuit, which could include a digital signal processing chip, generates a first signal that includes the right digital signal added to the left digital signal and generates a second signal that includes the right digital signal subtracted from the left digital signal. The circuit also generates a digitally pre-emphasized first signal, which includes digital pre-emphasis, and a digitally pre-emphasized second signal, which also includes digital pre-emphasis. The circuit transforms the pre-emphasized first signal to a digital BTSC L+R signal and transforms the pre-emphasized second signal to a digital BTSC L-R signal.
