A bandwidth-limited pulse (also known as Fourier-transform-limited pulse, or more commonly, transform-limited pulse) is a pulse of a wave that has the minimum possible duration for a given spectral bandwidth. Bandwidth-limited pulses have a constant phase across all frequencies making up the pulse.
Typically, these fences are 2.4 metres (7 ft 10 in) tall and send high voltage electric pulses through the palisade at a frequency of 1 Hz (one pulse per second). Palisade electric fences are used in most countries, particularly where there is little vegetation to short-circuit the fence or where the costs of security personnel are high in ...
Pulse compression is a signal processing technique commonly used by radar, sonar and echography to either increase the range resolution when pulse length is constrained or increase the signal to noise ratio when the peak power and the bandwidth (or equivalently range resolution) of the transmitted signal are constrained.
For a chirp waveform that sweeps over a frequency range F1 to F2 in a time period T, the nominal bandwidth of the pulse is B, where B = F2 – F1, and the pulse has a time-bandwidth product of T×B. Following pulse compression, a narrow pulse of duration τ is obtained, where τ ≈ 1/B, together with a peak voltage amplification of √ T×B.
The NFC wild-card game between the Los Angeles Rams and Minnesota Vikings is being moved to Arizona, the NFL announced Thursday. The game remains scheduled for Monday at 5 p.m. PT, but will now be ...
A new class of microwave pulse generation architecture, the RACE (Rapid Automatic Cascode Exchange) pulse generation circuit [1] [2] is implemented using low-cost monolithic IC technology and can produce pulses as short as 1 picosecond and repetition rates exceeding 30 billion pulses per second. These pulsers are typically used in military ...
A new trend gaining popularity among people trying to lose weight is microdosing the diabetes medication Ozempic. With approximately 70% of American adults meeting the criteria for being obese or ...
