Master thesis (pre-Bologna period)
Open Access
Covenantee: Norges teknisk-naturvitenskapelige universitet[ANGLÈS] This thesis deals with the implementation and analysis of different methods to generate a first-order directional microphone for source location and noise measurement purposes. The methods analysed include a ... -
Application of the Coupling-Of-Modes (COM) model for designing and manufacturing ladder Surface Acoustic Wave (SAW) filters
(Universitat Politècnica de Catalunya, 2024-07-11)
Master thesis
Restricted access - confidentiality agreementThe manufacturing filter process requires full knowledge of the linear and nonlinear properties of materials and resonator and filter configuration behaviour. Initial test structures, including not only individual resonators ... -
Application of the input-output equivalent sources method for the simulation of nonlinearities in TC-SAW resonators and filters
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Conference report
Open AccessA good understanding of the nonlinearity mechanism in SAW devices is a crucial aspect in the filter stage. Nonlinear intermodulation distortion (IMD) may lead to spurious signals falling into the receiver band and limiting ... -

New technique to cancel IMD3 in electroacoustic filters
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Restricted access - publisher's policyThis work presents a new technique to cancel third-order intermodulation distortion (IMD3) by using a low frequency injected tone to generate a second-order intermodulation product (IMD2) that fall exactly at the same ... -
Ultrasound-based flow measurement system for saline flux in a perfusion phantom
(Universitat Politècnica de Catalunya, 2023-07-10)
Bachelor thesis
Open AccessIn this project, local velocities of water inside a perfusion phantom have been measured by sending Ultrasound pulses and measuring the time it takes them to travel upstream and downstream. The difference in their propagation ...
