Study Notes
Modulation Techniques in Digital Communication
- Amplitude Shift Keying (ASK) is a modulation technique used in digital communication systems.
ASK Signal States
- The ASK signal has two states.
ASK Representation
- ASK represents Amplitude Shift Keying in amplitude modulation.
Amplitude Variation
- When the digital signal is high (1), the amplitude of the carrier wave increases.
Disadvantages of ASK Modulation
- A disadvantage of ASK modulation is that it is more susceptible to noise.
