psrr+

what is significant of PSRR+ is infinity and PSRR- is finite?
why?
thank u:D
 

what is psrr+

PSRR stands for Power Supply Rejection Ratio.
As you can imagine, an infinite PSRR means that absolutely no change in the power supply voltage will affect the output. Of course, this is an ideal situation, in practice the PSRR has a finite (though large) value, such that power supply variations and ripple will have some measurable effect on the output of the circuit in question.
 

infinite PSRR implies absolute no change in the o/p with reference to the ripples/ ac signal on the supply.

Practically, it is always finite.
