摘要：A known theorem, Nigam (2010) dealing with the degree of approximation of conjugate of a signal belonging to Lip𝜉(𝑡)-class by (𝐸,1)(𝐶,1) product summability means of conjugate series of Fourier series has been generalized for the weighted 𝑊(𝐿𝑟,𝜉(𝑡)), (𝑟≥1),(𝑡>0)-class, where 𝜉(𝑡) is nonnegative and increasing function of 𝑡, by 𝐸1𝑛𝐶1𝑛 which is in more general form of Theorem 2 of Nigam and Sharma (2011).
