Technical Electrodynamics| Zusammenfassung: | In paper described is a model of hardware component of a frequency-phase measuring systems meant to be used in distance, shifts and vibration parameters laser gauges. Laser emitter voltage is generated using a digital frequency synthesizer, and informative parameters of the system are determined by multiplying the voltage of the investigated signal and heterodyne with the following digital editing in the digital signal processor (DSP). In the proposed system as in any FMCW(phase type) system the evaluation of the frequency of it's output signal by continuous step change og modulation frequency is made. Developed a model transforming processes in visual programming language NI LabView has been developed of using NI Multisim components. The simulation mixing schemes based on dual-gate MOSFET. Proposed way of increasing the performance of FMCW system by using of the proposed schemes mixers. Defined the value of the error through the multiplicator devices (mixers) based on dual-gate MOSFET.
