Lecture - 36 Noise in Phase and Frequency Modulation systems

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
