This simulation demonstrates the working of a Differential Amplifier, a fundamental building block in analog electronics. It uses two input signals of different frequencies (1 kHz and 2 kHz) and shows how the amplifier outputs the difference between them. The waveform at the output clearly highlights the differential nature, amplifying only the difference while rejecting any common signals. This circuit is widely used in sensor interfacing, audio processing, and operational amplifier configurati
