To Learn the Parts of a Travelling Microscope and to read a reading
Distinguish, differentiate, compare and explain what is the Difference between QPSK and QASK modulation techniques. Comparison and Differences.
Differences between QPSK and QASK Modulation Techniques
| S.No. | Parameter | QPSK Modulation | QASK Modulation |
| 1 | Modulation Type | Quadrature phase moduation | Quadrature amplitude and phase moduation |
| 2 | Location of Signal Points | On the circumference of the circle | Equally spaces and placed symetrically about region |
| 3 | Noise Immunity | Better than QASK | Poorer than QPSK |
| 4 | Probability of Error | Less than QASK | More than QPSK |
| 5 | System Complexity | Less complex | More complex |
| 6 | Distance between the signal points | d = 2 sqrt(Eb) for N = 2 | d = 2 sqrt(0.4 * Eb) for N = 2 or M = 16 |
