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.
In digital modulation, an analog carrier signal is modulated by a discrete signal. Digital modulation methods can be considered as digital-to-analog conversion, and the corresponding demodulation or detection as analog-to-digital conversion.ccording to another definition, the modulation is a form of digital-to-analog conversion. Most textbooks would consider digital modulation schemes as a form of digital transmission, synonymous to data transmission; very few would consider it as analog transmission.
