May i know how to recognise Series-Shunt Feedback Amplifier, Shunt-Series Amplifier, Series-Series Feedbak Amplifier and shunt shunt amplifier. Thanks!
for series...the current remains unchanged as tat of the input ...and voltage is added or subtracted...
for shunt ...the voltage remains unchaged as tat of the input ...and current gets added or subtracted..
as a rule of thumb
x feed any y driven
let x=y=series ,shunt
so for all four combinations ,we can easily calculate input and output resistance.
(i/p and o/p)resistance will increases if it is series in(i/p and o/p):
and also it will decrease if it is shunt
the series-series / series shunt / shunt series / shunt shunt configurations have been well explained with reference to OPAMPS in the following book... please go through that :
