This simulation shows the three major digital modulation techniques: Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK). In ASK (also known as On-Off Keying, OOK), the amplitude of the carrier is switched on and off depending on the binary input. It is simple to implement and widely used in low-cost applications like RFID tags, optical fiber communication, and remote controls. In FSK, the frequency of the carrier changes between two discrete values to repres

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
