Abstract:
A pulse edge compression device, comprising:a first input for receiving a first electrical signal containing a succession of pulses, each pulse including a leading edge spread over a certain time interval;a second input for receiving a second electrical signal containing a succession of pulses, each pulse including a trailing edge spread over a certain time interval;a signal processing unit coupled to the first and to the second inputs, the signal processing unit being operative to;a) process the first electrical signal to reduce the time interval over which the leading edges of the pulses in the first electrical signal are spread;b) process the second electrical signal to reduce the time interval over which the trailing edges of the pulses in the second electrical signal are spread;c) combine the processed first and second electrical signals to provide an output signal containing pulses, each pulse in the output signal having a leading edge derived from a leading edge of a pulse from the processed first electrical signal and a trailing edge derived from a trailing edge of a pulse from the processed second electrical signal;d) release the output signal.
