Design comparison between HiperLAN/2 and IEEE802.11a services

Examensarbete, grundnivå · Linköpings universitet

This paper is a study and comparison between the two Wireless LAN (WLAN) standards HiperLAN/2 and IEEE 802.11a. WLANs are used instead or together with ordinary LANs to increase mobility in for example an office. HiperLAN/2 is an European standard developed by ETSI and the IEEEs …

Överföring av digital video via FireWire

Examensarbete, grundnivå · Linköpings universitet

Transmission of digital signals is today more frequently used than transmission of analog signals. One reason for this is that a digital signal is less sensitive to noise than an analog, another reason is that almost all signals today are handled in a digital format. This thesis …

Lågoffsetkomparator

Examensarbete, grundnivå · Linköpings universitet

Detecting small signals with a comparator demands that the total voltage offset is lower than the actual signal. The total offset includes the voltage offset in the comparator and the voltage offset that is created by the offset currents that flows thru the load at the …
