This simulation demonstrates the working of an Amplitude Modulation (AM) circuit using operational amplifiers. In this setup, a high-frequency carrier signal of around 100 kHz is combined with a low-frequency modulating signal to produce an amplitude-modulated output. The circuit consists of two op-amps, resistors, and signal sources arranged to mix and control the amplitude variations effectively. The oscilloscope display shows the modulated waveform in green, while the red outline represents t
