This shows Simulation of delta modulation using opamp. Delta modulation is used for efficient analog-to-digital conversion in low-bandwidth applications like voice transmission, audio encoding, and simple telemetry systems. It requires less data than standard PCM since it only sends change information (up or down), making it ideal for systems with limited bandwidth or processing power. #ElectronicsEducation #electronicsrd #deltamodulation #opamp | 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
