2. Abstract המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 2 In Cellular Activity Detection & Identification project, a system which can indicate cell phone activity and locate its transmitting source will be built. This book draws a process of learning, exploration, and implementation. Still, it is important to know that its only one process out of many, experienced by a variety of students, All for one goal.

3. System description המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 3 This system contains two main subsystems, the first of which is analogue; designed to receive electromagnetic signals, yet the second is digital and it will process the received electrical signals and calculate the source position in space. The scope of this book in general will be on the analogue part design and testing. A focus will be given on the practical implementation of the theoretical solution and its feasibility. Building such a receiving system that will/can include antennas, amplifiers, mixers, filters, VCO's and energy detectors forces the understanding of each part of the above. A sufficient understanding can lead neat assumptions and will give the ability to cast the knowledge to electrical configurations that suit our needs.
