Then, the division of the two signals is added to the arithmetic operation in the frequency discriminating circuit 6, so that the influence of the error of a discrimination point distance due to the time error of the discrimination point can be reduced. That is, the input two signals of the arithmetic circuit 5 are proportional to the discrimination point distance (r) so that the influence of the (r) can be removed by adding the division of the input two signals to the arithmetic operation of the frequency discrimination circuit 6. Thus, the error of the value of the output of the frequency discriminator 6 can be reduced, so that the operation of the AFC circuit can be stabilized.
