RF Power Amplifier Test System: for Interpolating-supply Power Amplifiers

The objective of the bachelor graduation project detailed in this thesis is the development of a system suited for testing radio frequency (RF) power amplifiers (PAs). This PA test system is in particular set up for testing two-transistor interpolating-supply amplifiers.<br/>Interpolating-supply PAs are efficiency-enhanced by employing multiple...

ADAS op het onderliggend wegennet: Een analyse van de potentiele veiligheidseffecten van ADAS en een simulatiestudie naar de effecten van ISA

Binnen de sector verkeer verschuift de aandacht voor intelligente infrastructuur via intelligente voertuigen naar lntelligente Transport Systemen (ITS). Tevens verbreedt de aandacht voor het hoofdwegennet (HWN) zich naar het onderliggend wegennet (OWN). Het OWN wordt hier gedefinieerd als aile hogere orde wegen die niet tot het HWN behoren. Dit...
