CRO in the X-Y mode to display the transfer characteristics for differential

In conclusion, there are a number of a number of things learnt in relation to the main objective of this experiment. From the experiment, we have been able to learn how to use the CRO in the X-Y mode to display the transfer characteristics for differential and common mode signals. From that we have been able to highlight the change of small signal differential gain with circuit unbalance together with the relative magnitudes of common mode and differential gain enabling common signal rejection. Through the experiment we have also been able to determine the limited common mode signal range in which rejection occurs. This experiment has also helped us to know how to measure and calculate the characteristics of amplifier for the differential transfer characteristics of a bipolar long-tailed pair, common mode transfer characteristics of a bipolar long tailed pair and the common mode range of a bipolar long tailed pair differential amplifier. This experiment has been a great success since it has enabled us to understand how devices with circuits of a differential connection behave in different scenarios and the findings can be useful in modifying the amplifier to function better of develops other devices. The transfer characteristics for differential and common mode signals are a major determinant factor in determining the efficiency and versatility of a differential amplifier.
