3.2. Convolutional Encoder

The viterbi IP core convolutional encoder.
Figure 7. Convolutional EncoderL = 5, N = 2 and polynomials GA = 19 and GB = 29. GA in decimal is 19, which is equal to 10011 in binary. The most significant bit of the binary representation is the connection at the input data bit; the least significant bit (LSB) represents the connection at the end of the shift register chain. The XOR function implements the modulo-2 adding operation
