| Q. |
can potentially provide spectral conservation through the use of multilevel signalling. |
| A. | m-ary psk |
| B. | mfsk |
| C. | ask |
| D. | dfsk |
| Answer» A. m-ary psk | |
| Explanation: in m-ary schemes, the spectral efficiency is increased by the factor log2 m.this is purely for m-level schemes which can provide multilevel signalling patterns. | |
