This code has been determined to be the best code for rate 1/2, K = 3. Convolutional Encoding: Example. 1.) The output selector (SEL A/B) now cycles through two states. First it selects the top modulo-two adder and sends its result to the output. Second it selects the bottom modulo-two adder and sends its result to the output. Example Continued
