Phase Shift

Some articles on phase shift, phase, shifts:

Lattice Phase Equaliser - Design
... Z is purely reactive such that Z = iX then the phase shift, φ, inserted by the filter is given by, The prototype lattice filter shown here passes low frequencies without modification ... That is, it is phase correction for the high end of the band ... At low frequencies the phase shift is 0° but as the frequency increases the phase shift approaches 180° ...
Time Stretch Analog-to-digital Converter - Comparison With Time Lens Imaging
... The lens imparts a quadratic phase shift to the spatial frequency components of the optical waves in conjunction with the free space propagation (object to lens ... imaged by a three-step process of dispersing it in time, subjecting it to a phase shift that is quadratic in time (the time lens itself), and dispersing it again ... when the two dispersive elements and the phase shift satisfy the temporal equivalent of the classic lens equation ...
Phase-shift Oscillator
... A phase-shift oscillator is a linear electronic oscillator circuit that produces a sine wave output ... amplifier element such as a transistor or op amp with its output fed back to its input through a phase-shift network consisting of resistors and capacitors ... The feedback network 'shifts' the phase of the amplifier output by 180 degrees at the oscillation frequency to give positive feedback ...
List Of Dutch Inventions And Discoveries - Inventions - 1933 Phase Contrast Microscope
... a medium other than vacuum, interaction with this medium causes its amplitude and phase to change in a way which depends on properties of the medium ... The human eye measures only the energy of light arriving on the retina, so changes in phase are not easily observed, yet often these changes in phase carry a large amount of ... although the phase variations introduced by the sample are preserved by the instrument (at least in the limit of the perfect imaging instrument) this information is lost in the ...
Scanning SQUID Microscopy - Applications
... to exp(-iφ), where φ is known as the phase of the wavefunction, this property can be also interpreted as a phase shift of π under a 90 degree rotation ... wavefunction must have only one value at each point, the overall phase factor obtained after traversing the entire Josephson circuit must be an integer multiple of 2π, as otherwise, one would obtain a different ... (and real) space, the wavefunction will undergo a phase shift of π ...

Famous quotes containing the words shift and/or phase:

    You’ve just fulfilled the first role of law enforcement. Make sure when your shift is over you go home alive.
    David Mamet, U.S. screenwriter, and Brian DePlama. Jimmy Malone (Sean Connery)

    The problem of the twentieth century is the problem of the color-line—the relation of the darker to the lighter races of men in Asia and Africa, in America and the islands of the sea. It was a phase of this problem that caused the Civil War.
