Query: The number of unimodular zeros of self-reciprocal polynomials with
  coefficients in a finite set   We study the number of real zeros of trigonometric polynomials in a period
and the number of zeros of self-reciprocal algebraic polynomials on the unit
circle under the assumption that their coefficients are in a fixed finite set
of real numbers.
