Differential Amplifier by the very name suggests that, the difference (algebraic sum) between two INPUT signals are measured. The computed difference signal is available at the OUTPUT terminals. The output is further amplified by the feedback resistance value in the form of gain.
Vout = A (V1-V2) Where Vout- is output voltage, A ? is gain of the amplifier, V1 is input signal 1, and V2 is input signal 2. This trainer has all the components necessary to study the difference amplifier principles using OP-AMPs and transistor configurations. This trainer has built-in power supplies, appropriate component values, Variable potentiometers. The connections are made using standard wires as patch cords. |
