Abstract:
1. A convolution encoder characterized in comprising: encoding object data generating means for generating bit values on the basis of input data; first and second bit registers for storing a bit value of a single inputted bit and outputting a stored bit value respectively when the bit value of the single bit is inputted; a first adder for processing an exclusive OR operation on a bit value from the encoding object data generating means and the bit value outputted from the first bit register; and a second adder for processing an exclusive OR operation on a bit value from the encoding object data generating means and the bit value outputted from the second bit register, wherein the encoding object data generating means switches at a prescribed timing the bit values for inputting to the first and second adders from bit values on the basis of the input data to bit values on the basis of the bit values stored in the first and second bit registers respectively.
