Applied Physics and Mathematics Annotation << Back CONDITIONS OF PHYSICAL REALIZABILITY OF ECONOMICAL AMPLIFIERS AND CONVERTERS OF AUTONOMOUS VEHICLES A.L. GALIEV, S.G. CHEKMAREV, I.А. STEPANENKO It is shown that in Autonomous devices individual use the minimum reconstruction error of the original signal is observed when using adaptive Delta code, a frequency-pulse-width, pulse-width and asynchronous Delta-modulation. An intermediate representation of the information in the devices of the third group it is better to use the adaptive Delta coding and pulse code modulations, since the intermediate conversion have little effect on the energy performance of electronic devices. Analytically grounded and determined the optimum values of sampling frequency at various ways of modulating the source signals with pulse-width and frequency-width-pulse modulation – fД ≥ 50, in the case of adaptive, multilevel, ternary, etc. the Delta-modulation – fД ≥ 100 kHz. Keywords: Delta modulation, Autonomous devices, information devices, reference channel, the feedback. Contacts: E-mail: galievanvar@mail.ru Pp. 03-10.
