signal pulse 100 and its characteristics in this example the pulse corresponds to a pure sinusoid in other words an unmodulated signal received at the time t 1 and ending at the time t 2 the parameters to be detected associated with the pulse are notably the time of arrival of the pulse usually designated by the acronym toa the pulse width designated by the acronym li and the center frequency of the signal forming said pulse the pulse may also be characterized when it is modulated by frequency and phase modulation parameters it may thus be advantageous to detect any phase jumps in a signal pulse and that is what the present invention proposes to do fig2 shows an example of a wideband digital receiver according to the invention comprising receiving radiofrequency circuits 200 201 a frequency measurement device ifm 214 a phase jump detection device 216 and a device for detecting and characterizing the pulses 213 the receiver comprises at least a receiving antenna 200 the signal or signals received by said antenna are amplified 201 then distributed over n digital processing channels on each channel the signal can be for example digitized on 1 bit by a flip flop 202 203 the passband of which covers the range of the band to be processed the n sampling frequencies.
