Abstract
This invention relates to an electronic device for taking the speed of a rotating member. In order to provide speed signals having a different degree of discrimination at the interior of a determined range of values, the device according to the invention comprises transducer means operatively connected to the rotating member to generate a first train of pulses, pulse generating means for generating a second train of pulses at a constant frequency, counting means for counting the pulses of said second train between two subsequent selected pulses of said first train, and a microprocessor for comparing the counted pulses with reference numbers comprised between predetermined minimum and maximum values corresponding to higher and lower values of a maximum speed zone of the speed range.
