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. |
