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
