Received data is sampled with a sampling pulse of a rate m greater than that n of the received data, and a minimum bit number of the received data is determined from a sampled output for estimating a signal transfer rate of the received data. The present method and apparatus can be applied to received data not involving a timing signal.

DETAILED DESCRIPTION In view of the drawbacks of such prior techniques, it is an object of the present invention to provide a method of and an apparatus for detecting a minimum bit number from the received data which can be used for estimating a signal transmission rate of received data even when a data signal not involving a timing signal is received.
To achieve the above objects, the method of estimating a signal transmission rate of received data according to the present invention employs a sampling signal having a frequency or rate greater than that of the received data.
The above and other objects, features and advantages of the present invention will become more apparent from the following description when taken in conjunction with the accompanying drawings in which a preferred embodiment of the present invention is shown by way of illustrative example.
