Abstract
A received signal having a series of T-spaced symbols having more than two levels is sampled at a rate that produces successive samples S, S, and Ssubstantially equally spaced by T/2. An output representing the difference between the sign of the sample Sand the sign of the sample Sis generated, and the value of the sample Sis offset so that the value of the sample Sapproaches zero. The offset value of the sample Sand the generated output are multiplied together in order to provide a timing error signal. The sampling of the received signal is controlled in accordance with the timing error signal.
