analog film

(redirected from analog resolution)

analog film

A plastic sheet with a photosensitive emulsion that comes in various formats for still and video cameras. When exposed to light, plastic-based film creates an "analog" of the actual scene. Film was never called analog until digital cameras came on the scene.

Analog Resolution
Analog film has a greater resolution than most digital camera images. For example, a 35mm analog frame may resolve up to 6,000 lines. Although digital IMAX theater cameras reach 7,000 lines, consumer HD camcorders record only 1080 lines. The granularity of analog film is based on the emulsion molecule size. The granularity of digital images is based on the number of horizontal and vertical pixels in the sensor. See digital camera and digital photography.

Within the IF section, the analyzer aligns the center frequency and gain of the analog resolution bandwidth filters, verifies the amplifier's gain and linearity, corrects any frequency drift and gain errors in the circuitry that drives the digital resolution bandwidth filters and ensures that the analog-to-digital (A/D) converter range is optimum and linear.
The new models support DVI resolutions up to 1600x1200 per display and analog resolutions up to 2049x1536.
