    effect of addition of poles and zeroes

    addition of poles when a zero is added...the root locus of the system ...moves to left of s=jw plane...hence stability increases.... when a pole is added the root locus of the system moves closer to s=jw plane...(assuming pole is not added far away from origin.....)hence stability...

    wat is the meaning of K=0 in root locus method

    we all know that root locus method is obtained by varying gain K from zero to infinity..... my simple doubt isnt K=0 meaningless since G(s) vanishes.... i would say K=0 is simply stated for mathematical purpose....am i right or wrong correct me

    PLL, Ossilators and Frequency Synthesizers

    frequency sintetizer schematic an oscillator,pll and frequency synthesizer all generates a particular frequency..... take two oscillators of same frequency but from different sources....though they are same in terms of frequency they need not have same phase...(remember rate of change of...
