Abstract:
A general approach is presented for the frequency-domain analysis of SC networks. At first, the sealing property of SC network is discussed. From the scaling property it is pointed out that the SC network ean be modeled by an analogue circuit consist...

Abstract:
A gain control loop which operates in a digital correlating receiver is described. The properties of the loop are analysed mathematically and the formulas to determine the sensibility and other parameters are derived. The static and dynamic features ...
