This simulation shows an amplitude modulation (AM) circuit using op-amps. The waveform above displays a high-frequency carrier whose amplitude varies with a low-frequency message signal. AM is widely used in radio broadcasting and communication systems. Apart from op-amp circuits, AM can also be implemented using diode modulators, transistor-based circuits, or digital techniques like DSP-based modulation. #ElectronicsEducation #electronicsrd #AmplitudeModulation | Electronics Education

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
