The Answer is

E _ { 5 } = \sum s _ { i } ^ { 2 } = 25 + 4 + 9 = 38 . \sigma _ { N } ^ { 2 } = 0.01 . S N R = 38 / 0.01 = 3,800 \rightarrow S N R _ { d B } = 10 \log _ { 10 } ( 3,800 ) = 35.8 \mathrm {~dB}

For Signal Sequence si=(5,−2,3)\mathrm { s } _ { \mathrm { i } } = ( 5 , - 2,3 )si​=(5,−2,3)

For Signal Sequence $\mathrm { s } _ { \mathrm { i } } = ( 5 , - 2,3 )$
