- Description: Convolutional coding is widely used in modern digital communication systems.We often get encoded data by using different polynomials having same constraint lengths (K).

How it works
We have two polynomials of 4th order and a shift register of 5 bits. we take input data of a single bit and put it in shift register on each clock edge as long as valid data bit is asserted. after this codeword is calculated by taking xor of the and of polynomial and shift register
How to test
apply clk,reset ,data valid and input data and do calculations to see if output is equal to the desired one
