Difference Between ASK FSK and PSK
| Parameters | ASK | FSK | PSK |
|---|---|---|---|
| Modulated Parameter | Amplitude | Frequency | Phase (180 Degree) |
| Number of bits/symbol | One | One | One |
| Noise Interference | Maximum | Less than PSK | Moderate |
| Bandwidth Requirement | Less than FSK | Maximum | More than ASK |
| Detection Complexity | Simplest | Simpler than PSK | Complex compares to FSK and ASK |
| Amplitude Variation | Varies | Almost constant | Abrupt changes at phase shift |
