Abstract: A device for generating pulses of high-precision programmable duration, whose particularity is the fact that it comprises:

-- first pulse generator means (1) which are suitable to receive in input a pulse generation command signal (IN) and to emit in output a first pulse for loading the contents of a register in counter means (2);
-- second pulse generator means (4), triggered by the first pulse in output from the first pulse generator means (1);
-- third pulse generator means (6), triggered by a second pulse emitted by the second pulse generator means and suitable to generate a third pulse to restart the second pulse generator means;
the second pulse emitted by the second pulse generator means (4) constituting a clock signal for the counter means (2) in order to produce a decrement in the counter means; the signal in output from the counter means (2) being the pulsed signal to be generated (OUT); the duration of the pulsed signal being determined by the content of the counter means (2).
