Learn how to do the whip in west coast swing dance from dance champion Robert Royston in this Howcast dance video.
modulation transfer function (MTF) a quantitative measure of the ability of an imaging system to reproduce patterns that vary in spatial frequency. The MTF is useful in predicting image degradation in a series of radiographic components.
SecurActive Performance Vision. Modulation is the addition of information to an electronic or optical carrier signal. A carrier signal is one with a steady waveform -- constant height (amplitude) and frequency.Information can be added to the carrier by varying its amplitude, frequency, phase, polarization (for optical signals), and even quantum-level phenomena like spin. carrier signal is one with a steady waveform -- constant height (amplitude) and frequency.
