Abstract :
The letter suggests that a simple fast digital encoder can be formed from the combination of v.c.o. and digital discriminator, automatically eliminating the complex logic processes of conventional fast baseband a.d. convertors. The technique is suitable for encoding video signals to 8 bits.
