Abstract
A data receiving apparatus. A plurality of A/D converters are used to convert a received input signal into digital signals having different sampling phases. Each of the digital signals is demodulated, and applied to a discriminator for obtaining a logic state from the demodulated signal. The logic state derived from the discriminator is compared with the demodulated signal producing the logic signal in a comparing circuit to derive an error. An error comparing circuit compares each of the errors, and a data selector responds to the error comparing circuit to select the logic signal showing the smallest error as decoded data.
