Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

Differential Amplifiers amplifies the difference between the applied input at both terminals. By connecting one voltage signal onto one input terminal and another voltage signal onto the other input terminal the resultant output voltage will be proportional to the “Difference” between the two input voltage signals of V1 and V2. The op-amp voltage comparator compares the magnitudes of two voltage inputs and determines which is the largest of the two.
