front porch – blank while still moving right, past the end of the scanline, sync pulse – blank while rapidly moving left; in terms of amplitude, "blacker than black". back porch – blank while moving right again, before the start of the next scanline. Colorburst occurs during the back porch, and unblanking happens at the end of the back porch.
This way the noise covers a bandwidth that is much wider than the signal itself. The resulting signal influence relies mainly on the filtering of the noise. To describe the signal quality without taking the receiver into account, the optical SNR (OSNR) is used. The OSNR is the ratio between the signal power and the noise power in a given bandwidth.
The display features a built-in 720p [4] FaceTime HD camera (replacing the iSight in the previous model), microphone, and stereo speaker system with subwoofer (2.1 channel). An octopus cable with Thunderbolt and MagSafe is permanently attached to the back of the display for data and charging MacBooks, respectively.
Full-spectrum photography is a subset of multispectral imaging, defined among photography enthusiasts as imaging with consumer cameras the full, broad spectrum of a film or camera sensor bandwidth. In practice, specialized broadband/full-spectrum film captures visible and near infrared light, commonly referred to as the "VNIR". [1]

While optical resolution, as commonly used with reference to camera systems, describes only the number of pixels in an image, and hence the potential to show fine detail, the transfer function describes the ability of adjacent pixels to change from black to white in response to patterns of varying spatial frequency, and hence the actual ...
Research has mostly focused on studying additive noise channels under certain power constraints and noise distributions, as analytical methods are not feasible in the majority of other scenarios. Hence, alternative approaches such as, investigation on the input support, [ 6 ] relaxations [ 7 ] and capacity bounds, [ 8 ] have been proposed in ...
There is a lot of debate on whether it is necessary to do the black balance every time. Panasonic 102 XB camera operating instructions manual suggests that black balance be performed when: The camera is used for the first time; The camera is first used after a long period of disuse; The ambient temperature changes greatly
