Aim: To make the student able to
-analyse and design high frequency wideband and tuned amplifiers, matching networks (filters) and oscillators, with discrete and integated components.
-understand noise properties of amplifiers in order to optimize the design.
-understand the more common modulation-and demodulation circuits and their properties.
