NTE7018
Integrated Circuit
Small鈥揝ignal Subsystem for Color TV
Description:
The NTE7018 is a TV subsystem circuit intended to be used for base鈥揵and demodulation applica-
tions. This circuit consists of all small鈥搒ignal functions (except the tuner) required for a quality color
television receiver. The only additional circuits needed to complete a receiver are a tuner, the deflec-
tion output stages, and a color decoder. The NTE1567 NTSC color decoder, and the NTE1754 verti-
cal output, are ideal complements for the NTE7018.
