Abstract
A method of automatically detecting the baud rate of an input signal and an apparatus using the method. A counter is started upon detecting a first transition of the input signal. The counter is stopped upon detecting a second transition of the input signal. After the counter is stopped, the measured count in the counter represents the duration between the first and second transitions of the input signal. The measured count is compared to a plurality of expected counts to determine which of the plurality of expected counts has a value closest to the measured count. The input signal is sampled using a baud rate based on the expected count having a value closest to the measured count.
