Anti-aliasing Filter in Hybrid Filter Banks
Hybrid Filter Banks allow wide-band, high frequency conversion. All existing design methods suppose that the input signal is band-limited and that each sub-band signal is sampled at 1/M times the effective Nyquist frequency of the input signal 1/T . To avoid aliasing in the sampling process, an analog anti-aliasing filter should be used in order to eliminate noise in frequency bands in which th...
متن کاملFilter basics: anti-aliasing - AN928
In a sampled data system, frequency components greater than half the sampling rate "alias" (shift) into the frequency band of interest. Most of the time, aliasing in an undesirable side effect, so the "undersampled" higher frequencies are simply filtered out before the A/D stage. But sometimes, the undersampling is deliberate and the aliasing causes the A/D system to function as a mixer. This a...

متن کاملOptomechanical design of multiscale gigapixel digital camera.
Recent developments in multiscale imaging systems have opened up the possibility for commercially viable wide-field gigapixel cameras. While multiscale design principles allow tremendous simplification of the optical design, they place increased emphasis on optomechanics and system level integration of the camera as a whole. In this paper we present the optomechanical design of a prototype two-...
متن کاملInnovative Use of Opsite Flexigrid™ for Digital Photography in Rhinoplasty
Standardization of photography in plastic surgery is fundamental for pre-operative surgical planning, comparative post-operative assessment, and demonstration of surgical results.1 In rhinoplasty, slight changes in patient or camera position can lessen nasal hump, vary nose size, and alter skin tension.2 In order to prevent these common errors, photographic standardization with high-quality equ...
