advantages and disadvantages of ASK.ASK stands for Amplitude Shift Keying. Both ASK advantages and ASK disadvantages are covered.
Following are the silent features of ASK modulation.
• ASK is digital modulation technique in which carrier is analog and data to be modulated is digital. Modulated output is analog.
• Here strength or amplitude of carrier signal is varied to represent binary 1 and binary 0 data inputs; While frequency and phase of the carrier signal remain constant. Voltage levels are left to designers of the modulation system.
