A feasibility study
… transmission lines and receiver. The driver send low amplitude differential signals via the transmission lines to the receiver that amplifies and converts it to a single-ended signal. The receiver has to be fast and be able to feed an output signal with high voltage swing. It is …
… hole size was 400 nm and the hole spacing was 600 nm. This is due to the high signal strength and to the fact that the phenomenon occurred within the measurement range of the instruments. Samples where designated with the name sPa where s indicates hole size in nm and a hole …
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 …
The report handles the transmission of signals from piezoresistive pressuresensors and thermocouple from a rotating object. This report also evaluates the possibility to collect data in a datalogger that rotates with the object. Telemetrics was previously used for …
… also present amplitude spectrum from various PWM patterns - generated by signals that have been pulse width modulated with a triangle- shaped wave. By showing the frequency-content, the decisions are eased for the engineers and technicians that are working with this kind of …
… gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7. This is the error rate that is demanded for several of the investigated standards. Comparison is also made of …
… subject of this thesis is the identification of parameters and the excitation signals needed for the identification of each parameter. The models and algorithms presented in this thesis work in a principle point of view. Despite this they work in varying extent for the different …
… thesis focuses on finding the best method to extract the content of a sampled signal regarding both simplicity and speed. Both amplitude and phase of each harmonic must be calculated. Is the proposed method suitable for the current computer system and how can it easily be …
… with. To reach the desired corporate image companies need to be aware of the signals they are sending out and how and what to communicate to the market. They need to look within themselves and their internal factors, since the signals are created within the company. Purpose: To …
… through the air some new security risks appear. It’s difficult to restrict the signals to a specific space and thereby a lot easier for unauthorized to eavesdrop or disturb the signals compared to a traditional wired network. Furthermore the wireless network could be abused for …
… hole size was 400 nm and the hole spacing was 600 nm. This is due to the high signal strength and to the fact that the phenomenon occurred within the measurement range of the instruments. Samples where designated with the name sPa where s indicates hole size in nm and a hole …
… a maximum transmission rate at 54 Mbit/s and they use OFDM to modulate the signal. This means that the physical layer in the two standards is similar. The differences between the standards are in the Medium Access Control (MAC) layer. HiperLAN/2 has a much more complex MAC since …
Anledningarna till att använda sig av en trådlös signalöverföring i en industri kan vara många, oftast handlar det om ställen där det är svårt eller omöjligt att ha en trådad förbindelse. I det här fallet är det en sedimenteringsbassäng där man tar hand om processvatten från …
Hur förskollärare anser att en blogg kan användas för att dokumentera veksamheten och främja föräldrasamverkan
… recording system to a digital counterpart. It is key that the video and audio signals remain synchronized, generator locked and time stamped. It is up to nine different video sources and a number of audio sources to be recorded and treated in such a manner which enables …
