what i did to measure the CMRR is...u pls tell me if i was right...
i first measured common mode gain with the circuitry made on breadboard using 4 resistors of 10 k each. one i kept as feedback resistor on pin no 2-6. and one resistor i grounded with pin no 3. remaining 2 resistors i kept at...
thank u...
now pls help me with this very basic concept....
when both the amplifiers are same in opamp why one treats as positive and another as negative...?
you did it right bt mathematically we calculate CMRR by th formula
CMRR= 20log(Ad/Ac)

i have a query..pls reply..
should o/p voltg increase with increase in i/p voltg frequency in case of inverting and non-inverting amplifier?

no we can not...
