Electronics and Communication Embedded Systems Difficulty: Medium

For small value of gain K, the root must be: If the characteristic equation of a closed-loop system is s 2 + 2s + 2 = 0, then the system is In a log amplifier the input is 'a'. The output will be proportional to A network consisting of a finite number of linear resistor (R), inducer (L), and capacitor (C) elements, connected all in series or all in parallel, is excited with a source of the form $$\sum\limits_{k = 1}^3 {{a_x}\,\cos \left( {k{\omega _0}t} \right),{\rm{were}}\,{a_k} \ne 0,} \,{\omega _0} \ne 0.$$ The source has nonzero impedance. Which one of the following is a possible form of the output measured across a resistor in the network? The working of an optical fiber is bases on
