20.500.12556/DKUM-50164 Macromodel of precise signal-phase meter This paper presents a precise macromodel of a signal-phase meter, which allows continuous phase measurement during simulation. It has been developed as a support tool during the design process of a signal-conditioning circuit for incremental position encoders. The development of a signal conditioning circuit requires precise measurements of small signal phases, amplitudes and offsets using the analog/digital circuit simulator. The phase measurement cannot be performed directly with a simulator, therefore an appropriate macro-model is needed for a circuit simulator. The structure of the signal-phase meter is based on the conventional signal-phase measuring method and is intended for the measuring of a cosine-signal phase with a known frequency. It recommends that the time variations of an input signal’s parameters (amplitude, phase, frequency, and offset voltage) are slow and small as possible. Rapid change of a signal’s parameters decreases the simulation result’s accuracy. A macro-model’s precision mainly depends on the chosen parameters for the macro-model and for the simulation. We show that with the proposed meter’s model, the phase angle can be measured with an accuracy of more than ±0,02%. macromodel signal-phase meter makromodel merilnik faze signala true false true Angleški jezik Slovenski jezik Znanstveno delo 2015-07-10 12:36:28 2015-07-10 12:36:28 2022-05-28 03:08:45 2021-05-09 03:25:01 2012 0 0 str. 1-7 Letn. 2012 2012 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1687-5591 621.37 517574681 16314902 10.1155/2012/856497 1687-5591 URN:SI:UM:DK:OXUEESGX Modelling_and_Simulation_in_Engineering_2012_Salamon,_Jarc_Macromodel_of_Precise_Signal-Phase_Meter.pdf Modelling_and_Simulation_in_Engineering_2012_Salamon,_Jarc_Macromodel_of_Precise_Signal-Phase_Meter.pdf 1 B439B3714165862971C145B9ADB9992C 8b9a96dfaec6f5ff9d47aeaad46e405067aacad11fb4bd080fdde56721a98a8c 3f98a955-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=112580 http://www.hindawi.com/journals/mse/2012/856497/ 1 https://dk.um.si/Dokument.php?lang=slv&id=74722 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
