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.
The aim of pulse modulation methods is to transfer a narrowband analog signal, for example a phone call over a wideband baseband channel or, in some of the schemes, as a bit stream over another digital transmission system.igital modulation methods can be considered as digital-to-analog conversion, and the corresponding demodulation or detection as analog-to-digital conversion. The changes in the carrier signal are chosen from a finite number of M alternative symbols (the modulation alphabet).
