   Sammanfattning : Transistors are used in all digital devices today. The demand of faster and smaller devices such as mobile telephones and computers constantly drives the develop- ment of smaller transistor technologies. Transistors can also be used in analog applications. Today there are commercial chips with both radio and digital sys- tems in the same package. LÄS MER

3. 2. Frequency Tracking Using Digital Cavities

   Kandidat-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Fredrik Zetterblom; [2017]
   Nyckelord :Digital cavities; Frequency Tracking; Technology and Engineering;

   Sammanfattning : Digital cavities are efficient algorithms for comb filters with very low computational costs. They have been used to precisely measure the amplitude and phase of high frequency signals (few giga samples per second) from data acquired by high speed digitizers 80 GSps. LÄS MER
