Digital Electronic MCQ Set 1 1. What is the value of |TN(±1)|? a) 0 b) -1 c) 1 d) None of the mentioned AnswerAnswer: c [Reason:] We know that a chebyshev polynomial of degree N is defined as TN(x) = cos(Ncos-1x), |x|≤1 cosh(Ncosh-1x), |x|>1 Thus |TN(±1)|=1. 2. The chebyshev polynomial is oscillatory in the range…
