Frequency chirp reduction in Mach-Zehnder modulators
(Universitat Politècnica de Catalunya, 2021-06-04)
Coursework
Open AccessWe present our study of the Mach-Zehnder modulator (MZM) and the transmission of pure tone radiofrequency signals through an optical ber link. Our results show that the detected signal at the receiver vanishes at a speci ... -
Terminal Control Of A 2-Link Robot Manipulator
(Universitat Politècnica de Catalunya, 2021-06-04)
Coursework
Open AccessThis paper describes a comparative evaluation of different controllers for a position regulation 2-link robot manipulator. The equation of motion for two link robot is a nonlinear di erential equation. The controllers, namely ... -
Boundary conditions and Rankine-Hugoniot condition in computational acoustics
(Universitat Politècnica de Catalunya, 2021-06-04)
Coursework
Open AccessIn this work we derive a procedure that permits the implementation of suitable boundary condi- tions in the nite volume method for problems in acoustics. Afterwards, we validate the procedure through numerical experiments ... -
