(cheb’ ∂ sh∂v) A frequency filter or uniformly spaced linear array in which elements are weighted according to Chebyshev polynomials. Such weighting equalizes the amplitude of minor lobes and gives a sharp cutoff. Called equal-ripple filter. See Figure C-3. Also spelled Tchebyscheff array. Named for Fafnutiy Lvorich Chebyshev (1821–1894), Russian mathematician.
