From this lecture, I have learned some important things.

1. Convolution encoding is one kind of channel coding.

2. For doing channel coding data can transfer smoothly. Because of data rate is high, signal to notice ratio is increased and we can reduce the bit error rate.

3. Code rare is k/n. Which is denoted by R. R=k/n. By this, we can measure the efficiency of the code.

4. Initially inside the shift register all values are 0.

5. For 1 input, we will get 2 outputs (u1 and u2).
