With some calibration done to know exactly how long to expose each “pixel” of the paper, the device can create black-and-white analog images from a digital photograph. [Muth] notes that this ...

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 ...

Therefore, digital signals may be mapped to analog ones using sampling, the process of measuring the signal at predetermined times. There are two important parameters related to sampling: The image ...

then convert the digital signal back to an analog output using a DAC. The image below illustrates the use of an ADC, a DAC, and a pair of filters in a digital signal processing (DSP) application.
