In the first paper we proved that on the cyclic groups of odd order d, thereexist non zero functions whose convolution square f*f(2t) is proportional totheir square f(t)^2 when the proportionality constant is an odd algebraicinteger of norm d whose both real and imaginary part are square roots ofintegers. We show here that the function f can be chosen to be equal to theconjugate of its Fourier transform.
