Since the frequency of the modulated carrier changes, the duty cycle of the resulting pulse train varies. That means there will be a fixed number of pulses, but by taking the average voltage of ...

Using a smart ultrasound pulse train, she reduced noise in contrast ultrasound images. Nawijn obtained her Ph.D. on this subject on 24 October with the defense of her dissertation "Bubbles and ...

It is now generally accepted that the use of a pulse-train waveform is virtually a necessity to detect small airborne targets in a land clutter background. [1] The processing can take the form of the ...

Pulse-pounding footage captured a near-death experience at an Indian train station when a mother and her two young kids fell on the tracks during the commuter rush.

The analog signal input controls the duty cycle of an output pulse train that switches on and off once during each cycle. When a high output is required, the pulse train remains on for most of the ...
